This ought to be a quickie answer.
I wanted to upgrade / flash the bios of a gateway model 510x. I obtained the updates from gateway's homepage for this model. I double-checked that the existing bios matched the type - it did. I made sure I booted to dos using a win98 boot disk, like they said. But when I then ran the iflash.exe file (from a second floppy), it said:
"This system does not support flash memory"
Luckily there was a slightly older update that ran from windows.
But what causes this error, for future reference? (remember, I double-checked that it was right for this PC)
