I have problems with installing Leopard Zephiroth 10.5.2 rev1 for AMD and would appreciate any suggestions on how to continue. I have reviewed a lot of other threads but nothing has helped.
My hardware:
Asus A8N SLI Deluxe
AMD Athlon 64 3200+
1GB RAM
2 SATA HDDs
1 ATA DVD
1 ATA CD-RW
M-Audio Audiophile 2496 sound card (I suppose it won't work but it's in the computer anyway, maybe I should remove it?)

I install including setting up my disks as:
2 partitions on each of my 2 SATA disks.
All partitions using Journaled HFS+
GUID boot
Installation is on rdisk0s2
Customizes with no SSE2/3 kernel, drivers for sound and Nvidia graphics etc
After install I reboot with the DVD still in the drive. (should I?)
I get a gray screen where it hangs.
I reboot again, press f8 and '-s'
Now I try (found in other threads):

cd /usr/standalone/i386
dd if=./guid/boot1h of=/dev/rdisk0s2 bs=512 count=1
(OK)
dd if=./guid/boot0 of=/dev/disk0 bs=400 count=1
(OK)
/startupfiletool /dev/disk0s2 ./boot_v8
(error saying something about unable to unmount cleanly)

I also tried booting without the DVD but then the computer will not boot at all so I suppose the Leopard installation is not active yet.

I also tried the permission repair routine but it fails because I can't find the sudo command. I seems not to be in the search path.

Ooops, should be boot problems of course.

Boot up with dvd
unmount any partitions on that disk with disk util
then do as above
cd /usr/standalone etc etc....

Thanks lanxxx. I did what you said and now I managed to do the "cd /usr/standalone..." routine. The problem is that I still can't boot. If I boot without the DVD notinh happens. If I boot with the DVD in the drive but don't press f8 it will start booting from the HDD. First I get the white Apple screen, then there is a quick flash of the "multicolored ball" and then a gray screen then black then gray then black and so on, i.e. nothing else happens.
Any suggestions how to continue?

for you boot you need to use fdisk command

check

after you can try to boot with -x it is safe mode

for the loop you can try the activation commands they are listed

its the giving it a root passwd and jumping the setup
