Tried to make partition bootable with fdisk and i only have "_" blinking.
Leopard is running fine once loaded, but Darwin is missing so i have to boot from dvd with
mach_kernel rd=disk*s*

Is it possible to install without EFI or is it required?
Skipping EFI during install may cause the problems i'm having with Darwin?

I have same motherboard and ac97 working fine. System profiler says no...

I installed it and everything went perfect, then i booted and it booted just fine, but when it goes to the blue screen just before u actually set up the account and everything, the screen turns black and all i have is a mouse, which moves, does anyone have an idea what this is or how i fix it? thanks

What? How?
What did u choose in installation?
System profiler says no device?
Do you see output in audio settings?
I tried to play movies and music but of course no sound...

my specs:
Asus A8n-sli premium, X2 3800,2x1gb kingston,xfx 7600gt,ALC850,creative audigy 2 platinum pro,2x80gb sata2 seagate@raid0,plextor 130a,plextor px-755a,enermax liberty 500w.LG 1980q

Hi everyone, installation went fine, and I was able to boot into the operating system with the DVD left in. However, upon taking the DVD out, I restarted and I was unable to boot back into the operating system. I tried setting up installation with MBR the first attempt and GUID the second (with it's own designated bootloader for each install attempt). However, neither of them were able to boot. Instead, I was left with Boot from CD screen.
I tried making the partition bootable by following the directions I used for my previous installation (10.5.1), but that did not work. Instead, for GUID, after the Boot from CD screen came up, it felt as it was going to finally boot, however, it went into a blank screen and the system restarted.
Another problem I am having is the fact that when I go into About this Mac, I can't see my processor info as others have said it will. I had to change that information manually. Please let me know what I should do. As always, I thank you very much for your support.

AMD EFI ??????? i dont know a MB that have this .
probably u can tell it to me :)

In third party drivers i installed ac97, chipset drivers (nforce4) and geforce kexts and nvinject to my 8600gt.

System Profiler says "No Built-in Audio" but System Preferences>Sound> says Line out AC97Audio (PCM) and all sounds working fine.

thank you very much for replying!
i did the same exept the nvidia kexts which where different due to my 7600gt.
my system profiler says the same but my sound settings show no output,no input and no sound can be played.

I will re instal hoping it will help :(

I'm having the same issue. It seems the boot loader never installs.. Once I fix the boot problem, I am left with no boot loader... I was able to get into the OS once, and that was with the DVD in the drive and no video drivers installed. I then proceeded to install the graphics update but before I could fix anything the HUD telling me to reboot shows up an I had to do a hard reset thus starting my problems all over again....

@crawle could you give your hardware specifications? like your mobo.
Could you tell us how did you connect your drives? I had a "still waiting for root device" error while booting
into AMD 10.5.1 image as well old JAS 10.4.8 image.

zamboo-thanks in advance
