hi everyone
want to thank Zephyroth for great work first)
I've successfully installed 10.5.1, it worked. When 10.5.2. appeared, i decided to do everything from scratch. So it began...
The installer bootloader stops at a grey screen with a sort of a "turn off" sign and a message like "shutdown or restart" in 5 languages.

I tried the -v mode, it says "unable to find driver for this platform: "ACPI".

my specs:
mb: ASUS M2NBP-VM CSM
Athlon 64 x2 5200
2 gb ddr2
ati radeon 2600 xt
separate ide-channel drive

thanx in advance. guess, it's something BIOS related..
