I've found in OpenBios dev/bios a good reason to hope i could spare the cost of a "physical" flashing device , and a ease using. That is to say getting LinuxBios building the .bin and flash the onboard BIOS via the dev/bios mechanism.
I have a via/epia and a SST39 series 20A (256Ko) bios chip on I'd thought I could read/write this bios with cat my.bin >/dev/bios but by insmoding bios.o. But i got a kmess coming from lines 123-126 printk code of bios.c "BIOS : No flash devices found" This resulting in a console message "Device busy" (that is, though, a bit paradoxal notfound != busy isn't it ? :) )
I can't catch what have missed me... Is dev/bios couldn't be used in my aim ?
Gratefull if experienced people could help me. Cordialy.
