Hi!
At last I've got Normal image loading (with release 2587).
Seems, the important difference between processes of Normal and Fallback images loading is that former obey CMOS data and later--not (uses compiled-in defaults).
Is this written somewhere?
So tweaking the CMOS data--leaved by the standard BIOS--with lxbios I get able to load normally.
Thanks to all who replied, in particular:
Stefan Reinauer Perry Wang Peter Stuge
BTW, VGA problem was resolved also (with Anton Borisov's AmiDeco tool). Onboard VGA rom size is indeed 36K--not 32 got with dd.
Best regards,

Good news! :) Glad you got it running.

I don't know, maybe it's in the FAQ?

Which parameters did you have to tweak to get the system up?

Looking at the serial console output after changing the boot_option value to "Normal" and the debug_level value to "Spew" in the CMOS, I've found that the system hangs near the very begining of load process after trying to find some memory (dram0).
So with lxbios I changed the max_mem_clock value from "200Mhz" to "400Mhz"--since I have DDR400 dimms inserted to the system--and got the system loaded.
Other changes were cosmetic, like giving meaninful values to boot_first ("HDD"), boot_second and boot_third ("Fallback_HDD").

Forgot to mention that to see the serial console output I also changed the baud_rate CMOS value to "115200"--since just this value was defined in the LinuxBios Config-s and I had set my serial console client (kermit) to wait connection just on this rate.
