 There is a problem with flashrom; it won't work reliably when the machine
 is booted under LinuxBIOS on the m57sli-s4.

 This is what I used to see:

 It works maybe 1 out of 10 times - it always works when booted with the
 proprietary BIOS. I can tell while it's flashing if it is good or not
 good: the speed of the flashing is moderately fast for a good flash. For a
 bad flash, it is either too fast, too slow, or it varies a lot during the
 flash.

 This is what I'm seeing today (with the latest rev of flashrom, 2744):

 Flashrom jumps from page 15 to page 224 while flashing, and then fails to
 verify. I've tried with several different chis (all of the same type
 though).

 I should note that I'm using a bios savior to swap flash chips, and that
 the socket has been soldered onto the board manually. But under the
 proprietary bios there is never a problem, so...
