Chaintech 6BTM + PIII-1GHz - hardware problems

Please help me.
I have a chainteck 6BTM mobo with a CPU Pentium III E 10x100 on a slot 1 adapter. Chipset Intel 82443BX (i440BX) and W977TF.
Two dimm sdram of 256MB, an Ati Radeon 7000 AGP 64MB.

OS: Windows XP SP2 - BIOS: Award 4.51

I tried your bios file for tualatin support but bios after post types "unknown flash type". (Checksum is also different).

I tried bios patcher on 6btm0817.bin and now bios when boot runs right cpu type.

But i have hardware problems because my system hans.
I think that the problem is the chipset i440BX.
When i run in VGA mode system is good.
And, i don't understand, why if i boot the first time my system hangs; if i reboot system works. (When i reboot bios doesn't show cpu and memory test).

п.с. помогите человеку, кто может - можно по-итальянски (тамошний он).
