Doesn't UF use "flat-realmode" (aka "UnRealmode")? I must have read it somewhere.
Porting it to PM wouldn't be such a hassle then, since memor access would be quite similar. You'd just have to go thru all realmode interrupt calls and create RM callbacks for them...

I got one, and it's a little marvel. But it costs more than one grand

Looking into M756T's bios modules with AMIBCP, I noticed that there is an option for a CPU/FSB setting of 66/133 in the "client" module, but that's not an available option in the actual setup. I'm pretty much interested on that option, since I use this machine to test RAM sticks and processors, as i...

If the jumper disables the WE pin, then all writing to the flashrom is disabled. Like in ECS's L7VMM2, for example.

I'm no expert on that, but afaik, the ACPI bios assigns all PCI devices to a single IRQ, and Windows' own ACPI HAL is responsible for internal IRQ steering. That's why all your PCI devices are listed under the same IRQ on Windows 2000, or are assigned to non-standard IRQs on Windows XP (like IRQ 23,...

I don't really know - it wasn't done by me, the first time. I can't tell, because I can't read the chip either.

Is it possible that the device isn't supposed to handle parts larger than 128kbits, therefore I should pull pins A14~A17 low ... Gonna try that later today.

I forgot to mention, I picked the W49xxxx because according to the datasheets, it does "boot up" on read mode, needing only Vhi on the OE and CE pins, just like a standard eprom...

Folks, I'm trying to fix an elderly video equipment, that has is firmware burnt onto a 27c128 eprom. Actually, the original eprom is a 2764, and my h/w has been reprogramed once with a 27c128. As I don't have the appropriate tools to erase and burn eproms, I've been thinking of swapping the eprom fo...

This one is for the desperate blokes like me searching for a BIOS from this long gone manufacturer. I've found out that the BIOS from a SOYO 6KE is a perfect match for the ACHITEC ACHI-160 (Intel 440LX), since they seem to share the same I/O chip, kbd controller and pci mapping. Having flashed a bad...
