ATI3870 EFI Strings problem

[Emilo]

I have installed Leopard from external drive as per Ls8 guide.

When booted, it showed apple logo and a black/white stop sign.

My SATA Drives are set to IDE mode in BIOS, so I installed JMicronATA_64bit (JMicronATA.kext & IOATAFamily.kext).

With JMicronATA_64bit installed did not get black/white stop sign but could not get my screen to work.

Assumed that my video card (ATI Saphire 3870) can't start from stock apple drivers so installed Natit 3870 (Natit.kext) from LTL v3 guide. After that system booted properly.

Then generated and installed EFI strings for my video card (ATI 3800 selection), ethernet and audio using EFI Studio.

Restarted from external HD, removed Natit 3870 (Natit.kext) and booted main drive.

While booting, it showed apple logo and got the same messy screen as before installing Natit 3870.

Installed Natit 3870 (Natit.kext) again from external drive.

Then main drive booted properly.

Here is what I found:

Audio and Ethernet (TEG-PCITXR) work properly.

USB devices work properly.

Time machine doesn't work - "The backup volume could not be found" message.

Sleep, restart, shutdown not working (reboot & shutdown fix not installed yet)

 

I don,t understand why ATI3870 EFI Strings are not working.

Can anybody help?
