Oh ... and _do_ _not_ try to flash the BIOS over a netbooted floppy 
image. I doubt you would, since dropping DOS onto the disk is so much 
easier (now, why didn't I think of that...), but let me assure you it 
does not go well if you try. As far as I can tell, DOS4GW seems to 
overwrite or disrupt access to the part of the memory the floppy image 
is sitting in, and the flash tool only notices AFTER it's erased the 
flash memory. Ouch.
