BIOS for the MSI EX610 notebook, board MS-163D, stored in a ZIP of only 389 KB. MSI designs these boards itself, and the MS-163D code is printed on the mainboard, so it is easy to confirm a match. Older MSI machines like this used small SPI or LPC flash parts, so check the chip type and capacity before flashing. Use a programmer for recovery after a failed update, compare image size against the chip and save a read of the original contents first.
