Well different makers make different BIOS. American Megatrends, Phoenix, and others. The codes will be different per chip maker. I think ASUS used Phoenix (key word.. THINK). Google the beep codes for phoenix (or go to http://www.bioscentral.com/beepcodes/phoenixbeep.htm)
if they use Award BIOS, then yes, 1long 2 short is a VC issue.
