Download links available in extended post.Some huge progress has been done on modding 10.4.8 kernel sources!
Mifki just gave us a taste of his work by sharing his undergoing dev kernel.
I had the chance to test it on my hack and it has booted to loginwindow.app
(which then hangs for some unknown reason yet).
Seems Mifki made it! It boots to the full GUI.
Check out a screenshot from his box:
JaS has done some amazing work again!
He just released his 10.4.8 combo updates for Intel/AMD bundled in 4 packages.
- 2 packages for Intel SSE2 only and SSE2/SSE3 users
- 2 packages for AMD SSE2 only and SSE2/SSE3 users
This means you can update from any OS X 10.4.x to the latest JaS 10.4.8.
A full 10.4.8 DVD is to be expected soon… Stay tuned 
Download them right here:
Download JaS 10.4.8 Intel SSE3 Combo Update
Download JaS 10.4.8 Intel SSE2 Combo Update
Download JaS 10.4.8 AMD SSE3 Combo Update
Download JaS 10.4.8 AMD SSE2 Combo Update
Important note for Intel SSE3 users only:
If you get an error where you can’t get past the blue screen, just do this:
Boot with following options: -v -f -s -x then type in
mount -uw /
mv /system/library/exrensions/r2d2.kext /system/library/extensions/
and let it boot up in safe boot
If you got a GMA gfx card:
While in safe boot mode, mount the 10.4.6/10.4.7 JaS install DVD
Run the following package:
/System/Installation/Packages/10.4.7.GMA900.Support.pkg
Run Disk Utility, repair permissions and reboot.
If you run Pro applications:
Open 10.4.7 combo update (from apple)
with pacifist (http://www.charlessoft.com)
Install the iokit.framework
Important note for Myzar DVD users:
You must apply the AMD combo packages only!
Even if you run on intel!

This kernel does NOT need HPET nor NX !!!
Get sources here: http://semthex.freeflux.net/download/
Change log: semthex.freeflux.net/changelog/
Instructions to setup your test partition: link
Instructions to compile the kernel: link
Important:
Semthex has not included the TPM key in the sources,
so if you want to run the GUI, you need to replace commpage.c.
This kernel doesn’t decrypt apple encrypted binaries.
You need the 10.4.8 decrypts to run the GUI.
Please don’t ask decrypts here.
It’s not legit while modding the open source code is.
The default value for FSB is 200 Mhz if you do not specify anything.
So you should check your motherboard spec and the CPU you are using.
I was booting with 200 Mhz but in fact needed 133 Mhz. (Pentium D805 is 533 Mhz).
Thus my clock was too slow, and sound was crap.
Let say your motherboard support 533 and 800 Mhz FSB, but your processor is 533 Mhz.
Then you should set FSB at boot to 533/4 = 133 Mhz.
It is very IMPORTANT that you set the correct FSB speed.
Mifki just released a new version of his 10.4.8 kernel.
Now you can specify the frequency of the FSB as a boot option.
fsb=<mhz>
Download here: www.filefactory.com/file/f618b4
Semthex kernel does also include the possibility at boot to choose a FSB frequency.
The default value is 200Mhz. If you want different value, you have 3 possibilities.
For 100 Mhz: use the -g boot option flag
For 133 Mhz: use the -y boot option flag
For 166 Mhz: use the -z boot option flag
Tips:
Once you know your FSB, you can put it as default value for your boot args. Just edit: /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
You should set this if using semthex kernel and 133 Mhz FSB:
<key>Kernel Flags</key>
<string>-y</string>

This one is for multi OS addicts like me.
I have a triple boot with 2 versions of OS X86 and Windows XP.
So how do I exchange files between OS X86 and Windows systems?
Under Windows XP, I use MacDrive to read/write HFS+ partitions.
But under OS X86, I must use a FAT32 partition to write data on a windows partition.
NTFS is not supported in writing mode.
I really want to get rid of that FAT32 partition and avoid the max 4 gigs file size limitation.
So here is the solution, use MACFuse to write to NTFS file system.
