Can't write or Erase on Abit IC7

[Anders Jenbo]

Hi, i'm trying to use a Abit IC7 to cross flash the BIOS for another
board but neither erase or wirte works.
The chips that i am trying to flash is a SST SST49LF004A, I am able to
read it's content just fine.

Any ideas what might be the issue here?

I don't know how much help this is, but I did notice:

Probing for SST SST49LF004A/B, 512 KB: probe_jedec_common: id1 0x9d, id2 0x6e

Found chip "PMC Pm49FL004" (512 KB, LPC,FWH) at physical address 0xfff80000.

Probing for PMC Pm49FL004, 512 KB: probe_jedec_common: id1 0x9d, id2 0x6e
Found chip "PMC Pm49FL004" (512 KB, LPC,FWH) at physical address 0xfff80000.

That's definitely a PMC ID and it passes all flashrom safety checks, so
either the chip is mislabeled, something is really confusing flashrom to
an extent which is thought to be almost impossible, or the chip is
indeed a PMC Pm49FL004.

PMC Pm49FL004 is the original BIOS. I am trying to cross flash a norther
chip, just didn't put it in the system when i made the files logs.
The SST49LF004A has also been tested for all operations so it must be
something with the board.
