[=-Devin-=]

whats up with the "holes" and why is the color inverted?

[keeptruthfree]

there are hundreds of screenshots on this site

made by the same method - digital camera shooting the screen

- they even ALL have the same glare

 

I inverted them so I wouldn't burn up all my toner when printing.

 

nice look, eh?

[=-Devin-=]

well, anyway.

Make sure if you have sata and ide (sata for hdd and ide for dvd) make sure dvd is not slave. set it to master.

[keeptruthfree]

 

 

 

okay... so I edited the AppleVIAATA kext to include the right code...

 

now it's not VIA UNKNOWN anymore... it's via known!

 

so why won't it find the root device? - it's known!

 

c'mon!

[dying4004]

keeptruthfree: brocud u plz tell me what did u put in ur modified appleviaata.kext ?? i am using p4m900m2 mobo so it shud be similar to urs one. so i also need to modify my appleviaata. cheerz

[dying4004]

bro........... i have added modifed Appleviaata.kext in my kalyway install dvd but still i am facing STILL WAITING FOR ROOT DEVICE problem. cud u plz look at my attached pictures as u have very similar mobo as mine. mine is msi p4900m2. cheerz bro

 

[OnePlane]

I need to know what to put where. The P4M900 is driving me crazy! SATA won't do it's job (neither does audio or lan)

[OnePlane]

Fixed it Device 5372 Vendor 1106 needed to be added to the VIAATA kext for my special(?) version of the Via VT8237.

[XweAponX]

I have a Biostar P4M900-M4... And I got the same problems...

 

Is your ECS MB he same as my Biostar MB?

 

I found a "how to fix" the VT8237A in here somewhere, written by a 14 year old girl, I tried to print the page and it crashed my IE.

 

And I did not have it bookmarked... Anyone know of a post like that anywhere? I'm going nuts searching for it, she had what looks like a way to get the device detected.

[fernvick]

Hey guys does anyone know how to fix this issue <still waiting for root device> Thanks in advance!!

[r0fflew0ffles]

If you pop in your install disc and copy all the ATA kexts over, it might solve the problem.

 

I found this floating around somewhere:

cp -pr /Volumes/*DVD NAME*/System/Library/Extensions/*ATA* /Volumes/*HD NAME*/System/Library/Extensions/

where *DVD NAME* and *HD NAME* are the names of your install disc and mac hard drive.

then,

chown -R root:wheel /Volumes/*HD NAME*/System/Library/Extensions/
chmod -R 755 /Volumes/*HD NAME*/System/Library/Extensions/
rm -rf /Volumes/*HD NAME*/System/Library/Extensions.*

[kaswistry]

I have the same problem with a P4M900T-M2.

 

I think people here have figured it all out.

 

Can anyone please help?

[OnePlane]

You need to add the pci ID's to the plist in your sata/ahci kext.

 

If you do not know how to do this, you are not smart enough the run Mac OS X on a standard PC.
