[LinuxBIOS] flashrom with SST49FL080A

[Nicholas Veeser]

So I have what I thought was an 8MB flash device on my motherboard.  (Tyan
s2895)
with this I am using the RD1-LPC8 as a backup.

Well for my first test I read the flash from the original ROM.
Flipped the switch on the RD1 and wrote it back.
This did not seem to work.

Looking at the files that I created from flashrom, it seems that flashrom is
only reading 1024k of the device and storing that in a file.

Is that on purpose?  Why is the file not 8MB?

This is correct. 8MB should be read as 8MBit = 1Mb.

The file is 8M-bit, ie 1M-Byte (8bits=1Byte). This is correct.

Could you send any error messages that you got from flashrom?
