Hi,
I have an EPIA 5000 mainboard
(http://www.viavpsd.com/product/epia_mini_itx_spec.jsp?motherboardId=21), which uses a SST39SF020A-70-4C-NH BIOS chip.
Is it possible to flash this chip using MTD? If so, can someone offer
some pointers?
Thanks,
Surj

Yes, probably -- you need to know how to enable the WE# and write-enable
lines to the flash chip, which are often hidden deeply in chipset magic.
See the other BIOS map drivers, e.g. ichxrom.c and l440gx.c, for
examples.
