BIOS Updates forum

When i start my compyuter i get "Unknown flash type" message and afters when i install driver for my tnt2 grafic card on restart my screen become blank. I try to flash bios with varios memory writers and atc0708b bios but i always get "Erase Chip Fail" message. It's biostar m5atc motherboard. What more can i do?

Is there an option to enable/disable BIOS updates in the CMOS setup?
Is there a jumper that does the same? (check manual)
What type of BIOS chip do you have? (look at the chip)

I've looked in Cmos setup and motherboard but there isn't such a option. I have Award chip (pci/pnp 586). Does anybody know where can i buy a new one, can't find it on biostar page.

That means, "pull back the Award sticker and tell us what writing is underneath on the chip."

The numbers on bios chip are
MX T9748
28F1000PPC - 12
M2111

Well, that looks like a 12V 1Mbit flash ROM to me. The manual, as you say, does not mention any jumpers or CMOS settings to enable.

Can you get into CMOS settings ? If so, is system BIOS shadow enabled ? Try turning this off when you flash.

I try that but the result is the same. Thanks for the tip maybe you now somthing else about this problem that I can do.

What happened with the PC just before the "Unknown flash type" message started appearing ?
Does the message appear every time you start the PC or when flashing ?
Does it appear before the memory count screen, on the memory count screen , or after the memory count screen ?

The message appeared after I tryed to flash bios, after the memory count screen before windows logo screen.
