After weeks spent in internet to find my motherboard model (my computer was bought in MediaMarkt - electronic mall known across the europe) I HAVEN'T FOUND THE MODEL of my motherboard - it has no sticks, no model number, anything on PCB. The BIOS string is "05/28/2002-P4X266-8233-ID6LWE0CC-00" (google fails when trying to find this string) it is CHAINTECH looks identicaly to ES-675M (9VIF),

Socket478, uATX
P4X266 w/8233 SB,
2xDDR PC2100 266MHz,
3xPCI,
AGP,
USB1.1,
2xUDMA100
but my motherboard doesn't have ISA (which CHAINTECH claims to be optional) slot and doesn't have onboard VGA (no option to activate in BIOS). CHAINTECH's support is crappy. They DO NOT respond e-mails. I downloaded bioses for ES-675M from chaintech's site and bios for ES-675B from wimsbios ftp (Thanks KURIAKI) but none worked for me. Since now i put my faith in You - forum users. Help me identifying this mainboard.
