The following is from forum member newdeal at MyHPMini, this guide is to install Leopard 10.5.5 using iDeneb. This is not a “concrete” guide so please help us by making some changes to it.

hpmini 110 white Leopard15ohy8m Leopard

Ok So I followed all the directions and had a ton of problems installing on the mini 110 because the instructions were not complete so here are a working set of proper directions that is basically the best you can do at this point on a mini 110. This is MOSTLY copied from the BPL guide but there are differances, the links to files don’t work just get them from the BPL guide. I did this on a PC so the directions for the mac are probobly right but I can’t confirm it. I hope this helps.

This guide will be for the iDeneb install method. There are people out there who have been able to use a Leopard retail disc but I have no knowledge on how to do that, so I’ll tell you what worked for me and many others.
First off, you have two options for installing OS X onto your Mini. The USB Drive Method, or using an external optical drive via the USB DVD drive method. I ended up trying both after my Mini stopped recognizing my DVD drive.

Things you will need
1. A HP Mini 110 series unit with at least 16GB or greater disk space (any model or OS; they all work) (NOTE: Make sure Bios is Version 0.5, won’t work if V0.3 is used)
2. An 8GB(or larger) USB drive OR an external USB DVD drive
3. A USB mouse
4. A copy of iDeneb v1.3 (NOT v1.4)
5. The HP Mini OS X Essential Files
6. Optional, but helpful: an additional USB drive to transfer files with

The most important thing you need to do is find a copy of the iDeneb OS X install DVD v1.3 disc image. Take a quick trip to google to find the iDeneb v1.3 image.
NOTE: you may also find iDebeb v1.4, but it doesn’t seem to play nice with the Mini for some reason so steer clear.

Create an iDeneb Installer

A. MAC via USB Drive
1. Open up Disk in /Applications/Utilites/
2. Select the drive you will be using in the left hand pane.
3. Click the “Erase” tab
4. Under “Volume Format” select Mac OS Extended (Journaled)
5. Click the Erase button
6. Click the “Restore” tab
7. If you havn’t already, go to your iDeneb.iso and double click it.
8. Back in Disk Utility, you should see the iDeneb.iso in the left pane with another image under it with an apple logo on it.
9. Drag the image to the “Source” location
10. Drag your drive you have erase to the “Destination” location.
11. Click Restore
12. Open up UInstaller and select your newly formatted drive
13. Check the “Install PC_EFI v9 Chameleon Edition 1.0.12
14. Click Install

B. USB DVD via OS X / working hackintosh
1. Find your iDeneb.iso and double click on it.
2. Open up Disk Utility. It’s under you’re utilities folder in your applications folder.
3. Click on your iDeneb.iso in the left pane of drive.
4. Click the “Burn” button on the top of the window.
5. Plug in your usb drive/DVD drive into the mini and reboot.
6. When the HP Logo appears, hit f9
7. Select your USB/DVD drive from the list of boot devices

C. USB DVD via Windows
1. If you don’t have one already, download an ISO burning program. Googling brings up this one:
2. Select the iDeneb.iso as the source, or open up the iso via your iso burning program.
3. Insert a blank DVD into the drive and burn.

D. USB Stick via PC / Windows
This can be done but it isn’t any faster and much more frusterating, if you don’t have a dvd drive for your mini I reccomend you get one and install OSX then return it because its way less frustrating but if you want to try this here are some ways. I followed these steps but they seem to work better for some brands of usb sticks than others

1) Format your usb stick to fat 32
2) Make your usb drive bootable: there are a couple utilities you can use to do this, I can’t remember which I used because I had to do this so many times to get it to work (it did but using the DVD is so much less of a pain). Google for the utilities, one is a utility from HP that allows you to boot your flash drive, tis not hard to find, the other one is called unetbootin-windows-357.exe. If you use the second one you need to select FreeDOS from the drop down on the top left, and then at the bottom set it to the drive letter of your jump drive and start it. Don’t bother thinking this program will write the iso to your drive also even though there is a spot called iso it won’t work. It will copy four files to the drive, go to the drive and delete these files once its done and you should have a bootable stick.
3) Use a program called ddmac to restore the iso to the stick. The interface is really weird and if you just try to use it the start button will be greyed. This is what you do
a) select your iso file
b) deselect the box that says tboot.ini boot.ini with a bunch of other question marks or something
c) deselect the box that is beside the drop down area where you select your drive
d) select your thumb drive from the drop down list
e) reselect the box beside the drop down menu again
f) press the button right beside this box and it will start

DO NOT TOUCH THIS, if anything happens it will crash, if you click on it, if you move it, if you click something else, if vista pops up the UAC menu or the you have updates menu, everything will crash it so let it work and dont touch it. Keep an eye on it to make sure it completes ok, if it crashes start from the beginning with formatting this drive and try again. If you get a message saying your drive is write protected part way through your usb stick is faulty and you need a new one.

Now reboot your computer and press f9 and select your usb drive to boot from, if you are lucky it will boot. Mine did but like I said I had to do this so many times because of crashes and a faulty usb stick that I can’t remember if I used the HP util or the other one so if one doesn’t work try the other

Install Mac OS X

DO NOT try to install OSX while leaving XP intact, it will not work so just abandon that idea and get rid of XP all together. If you want XP back later then you will have to reinstall it (not sure how since the mini doesn’t come with a cd)

1. The installer will now begin. Wait at the apple logo until a language selection screen is shown. Select your language and hit next. (hit tab once then space – if you can’t see the button at the bottom of the screen due to the Mini 110′s 576 pixels vertical resolution)
2. Go to the top of the screen where it says utilities. From this menu select “Disk Utility
3. Click on the Mini’s Hard drive in the left pane.
4. Click on the “Erase” tab
5. Under Volume format, select Mac OS Extended (Journaled)
6. Click Erase
(NOTE: If you plan on ever dual booting or wanting partitions on your drive, now is the time to do it. You wont be able to partition/resize your drive after the install. If you would like to dual boot, go to thepartitiontab on you HD, and click the + button. Its best to format this to Fat32 (MS-DOS) because its more universal. NEVER assign this as free space or it will disappear forever and will be useless unless you format your whole drive)
7. After erasing is complete, exit Disk Utility
8. Now click next and select your newly erased hard drive as the destination. (two tabs and space to click next)
9.On the next screen you will see an option at the bottom that says “Customize”. Click on it (first click the drive, then click somewhere else so its highlighted in grey and hit tab three times then space) and apply the following patches:
a. Expand “fixes” and select: (1)acpi, (2)cpu, and (3)remove firewire
b. Under “patches” expand chipset and select (4)ichx fix
You can now continue with the installation. Feel free to add any applications that are included with the installer but they are not necessary.

After sitting at the install screen for a while your computer will reboot. If you let it go it will tell you migration assistant can’t run due to the screen size and then it will load osx. YOU DON”T WANT THIS TO HAPPEN so hit enter as soon as the boot loader appears

1. Type “-s” and hit enter
2. Wait for the text skim by until it stops. Then type “/sbin/fsck –fy” and press enter
3. Once it says “File System was modified” type “/sbin/mount -uw /” with spaces
4. Next type in “passwd root
5. Now type in whatever password you’d like, twice, pressing enter after each time.
6. The type “touch /var/db/.AppleSetupDone” being sure not to forget the . or Caps
7. Now type “reboot” and hit enter

OSX will load

Installing Kernel Extensions

you will be prompted asking for a user name and password after the apple boot logo. User Name is “root” and password is whatever you set it to. Now that you are in OS X:
1. Click “System preferences” in your dock. It’s gray and looks like gears in a square box.
2. Click “Accounts
3. To the far left there is a “+” sign. Click it.
4. In the username box type whatever you like. DO NOT SET A PASSWORD.
5. Under “New Account” it should say Standard, but change it to Administrator.
6. Click Create account. It will prompt you asking if it’s OK to not have a password. Click OK.
7. Under the list of accounts to the left, click “Login Options
8. Under “Automatic Login” select the new account you made.
9. Reboot

Make Mac OS X on your internal hard drive capable of booting on its own

You should now be in OSX again, but this time you’re under you’re account instead of root. Now open up UInstaller.
1. Select your Hard Drive under Drives
2. Choose OSx86_Essentials as the package to install
3. Click “Apply kext package
4. Click “Install PC_EFI v9 Chameleon Edition 1.0.12
5. Hit Install

Now lets go ahead and apply the DST Patcher to get ready to update to 10.5.7. Open up the DST Patcher GUI.
1. Select “Darwin/Mac OS X
2. Select “New HPET Option
3. Select” Apply DSDT Patch to:
4. Select your Hard drive.

Install kexts to make hardware work.

Now let’s get wifi and all the fun stuff working. Open up OSX86Tools.
1. In OSX86Tools, click on “Repair Permissions” then click the button to perform the selected action
2. Click on “Install kexts” towards the bottom right
3. Find the kexts folder on your flash drive. Select the THIRD(excluding AppleGMA950.kext and AppleIntegratedFramebuffer.kext)one.
4. Shift+Click the last one to select all (excluding the two mentioned).
5. After the installer completes it will ask you reboot. Just click on OK and Cancel on any dialog boxes that appear.

Update to 10.5.7
You should now be OSX again after reboot. Here’s where things could go horribly wrong, or awesomely easy. There are two methods that can be done. Update to 10.5.7 via Software Update or downloaded updater (DMG).

A. Software Update Method:
1. Connect to your wifi network. If you don’t know how, its should be the symbol farthest left at the top right of the screen. Looks like a wireless bar signal
2. Go to “System preferences” again.
3. Select “Software Update
4. Click “Check Now
5. After they all load, uncheck all of them EXCEPT for “Mac OSX Update
6. Click “Install
7. Go through all the prompts. It will start to download then reboot. The download may take a while depending on your Internet connection.

B. Downloaded Update (Mac OSX 10.5.7 Combo Update) Method:
1. Copy the downloaded 10.5.7 Combo Update to the Desktop.
2. Double click it to mount the disk image.
3. Run the updater by double clicking it.
4. Go through all the prompts. It will start the installation process. It will reboot twice.

If all went well, you will be in OS X after rebooting itself a couple times. Be patient. If not, you’ll be sitting at the apple boot logo for a while wishing you had followed the guide more closely. If it fails, you have to do a complete reinstall. Start from step 1, at the top of the guide.

If you are in OS X congrats! Time to get out the USB Mouse and get your keyboard and track pad working.

Mouse and Keyboard Fix
Plug in that usb mouse you have. Be thankful you did not set a password if you are not foruntuneaute enough to have a usb keyboard.
First, run the VooDooPS2 Controller package. When prompted, make sure to check that box that says trackpad. Go through all the prompts until it’s installed. Reboot.

Now with working trackpad and keyboard, Open up OSX86 Tools again. Go ahead and reinstall all the kexts in the kext folder.
1. Click on “Install kexts” towards the bottom right
2. Find the kexts folder on your flash drive. Select the first one.(this time select ALL BUT ONE kext — Do not install the Intel GMA kext, it will disable your screen)
3. Shift+Click the last one to select all.
4. After the installer completes it will ask you reboot. Do it.

Enable Quartz
To enable Quartz open OSX86 Tools and click the Enable/Disable Quartz GL button. It will tell you the current status. If its disabled, feel free to enable it by clicking the button that says “Enable Quartz GL“.

Fix CPU (Allow dual-core)
If you start ActivityMonitor before doing this you will see that OSX only sees 1 processor (press the CPU tab below te process list). To allow it to use the second core do the following:
1. Log in as the admin user (logout your current user then select other at the login screen and type username root and the password you set for it)
2. Goto finder and select the drive you installed osx on and direct yourself to /Library/Preferences/SystemConfiguration
select the file and right click and copy the file, paste that somewhere else as a backup
3. open the file with the text editor (the default program) and select where it says something like cpu=1 -f and change the number 1 to the number 2 so that it reads something like cpu=2 -f instead
4. save the file then reboot your computer

Enable Quartz Extreme (10.5.7 only)
1) Download these kexts (download/file.php?id=248)
2) Go into OSX86 Tools, and select Install Kexts.
3) Browse to your download location, and install ALL of the kexts.
4) Once it is done installing, it will ask you to reboot. To avoid problems, click cancel, and, still in OSX86 Tools, go ahead and repair permissions. Be prepared for this to take a while, so don’t get worried if it does. It is normal.
5) Reboot when Repair Permissions is complete.
Also, all credit goes to Le Maurien19 for this one.

You are Done!
