Can I use embedded Flash ROM to update (Slic 2.1 modified) system BIOS ? Updating BIOS within BIOS ROM itself. (My board is ASRock, they called this utility: Instant Flash) So, I don't need any O/S (DOS/Windows) to BIOS Flash. Thx.
You can but it may not properly update the BIOS with SLIC 2.1. I would highly recommend that you Flash from DOS with the Flash utility from ASRock.
