Am at a loss as to where to look for help on this one. Recently aquired a Gridcase 1520 for some old DOS programs that I still need to run to interface with some machine PLC's. Need to boot from the "A" drive because the software can't be installed on the "C" drive. HOW DO I GET TO THE BIOS SETTINGS?.... I've tried all the normal stuff, CTL.S, ALT.S, etc., but nothing I do works...... (Have also tried to swing a cat over my head three times while facing east, but that only resulted in a clawed arm on my part!) Thanks in advance.............. .
