I ran flashrom on an asus P4P800-VM motherboard and got this error:
tux tmp # flashrom -w P4PVM1018.rom
No coreboot table found.
Found chipset "Intel ICH5/ICH5R", enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Calibrating delay loop... OK.
Found chip "SST SST49LF004A/B" (512 KB, FWH) at physical address
Flash image seems to be a legacy BIOS. Disabling checks.
Writing flash chip... ERASE FAILED at 0x00007810! Expected=0xff,
Read=0x3c, failed byte count from 0x00000000-0x0000ffff: 0x8732
Your flash chip is in an unknown state.

as I can see are you using one port of an FT2232H for the SPI programming. Unfortunatly for germans, the chip and the converter board is only aviable from Digikey. Is it also possible to only use full speed with FT232 or even low Speed and V-USB?
If high speed is necessary, can the program be changed that it works with http://www-user.tu-chemnitz.de/~heha/bastelecke/Rund%20um%20den%20PC/USB2... ?
Thank you in advance.

A successful flash chip operation is closely related to a few factors
other than the flash chip - southbridge, embedded controller, special
enabling operation of a particular board and the flashrom revision. Shall
we include other related information in the chip status table? Let us
put aside how to store the table first.
Any idea of what algorithm and bytes to use to update the CRC/Checksum
in the flash image?
The mac address is stored in the image. I have written a script to
update the mac address and know where the CRC/Checksum is. I have tried
various algorithms (those supported by Hex Workshop- Checksum-8 and -16,
CRC-8 and -16, etc. w/1's and 2's complements) but am unable to
duplicate a known checksum.
Hardware is a Kontron ETX Express module, flashrom reports: 'Found
Chipset "Intel ICH8M-E" ...', 'Found chip "SST SST25VF016B" ...'
Thanks in advance,

OK, so it is not ITE IT87.

Ah yes. That's a limitation of the DOS port of flashrom.
Usually the SB600 SPI base address is near the top of the address space
(4 GB). On your board it is below 1 MB, and AFAIK Rudolf said that we
can't map any region below 1 MB as uncached due to CWSDPMI/DJGPP
If anyone has an idea how to overcome these limitations, we can fix
flashrom for this special case.

Michael? Is there a good way to handle this?
