This is BIOS update ACR9CE00-M01-0304-R04-E8 for V12LC(-II) ACER computers. It is supposed to add support for(recognition of) Pentium 150mhz CPUs according to ACER's webpage. ( It does not add large HDD support as I had hoped.)
This is just the *.bin file. Copy it and the Award flash utility to a bootable floppy disc.
