[LinuxBIOS] Getting Friendly with Flashrom

[David H. Barr]

I'm trying to get Flashrom to flash a legacy BIOS image to the RD1
slot on a BIOS Savior PMC4 (thanks Eksidtata!), but I must be missing
something...

* I got flashrom checked out, compiled, and make installed.
* I show that both the W39V040B (ORG) and Pm49FL004 (RD1) are supported
* I've tested that a loose PMC Pm49FL004 is compatible with my mainboard
* I've tried issuing a flashrom line three or four times in sequence

However, I cannot get a successful write.  Any suggestions?  Excerpt follows.
