Hi.
I have an Ambra Sprinta, circa 1991-1992, running MS-DOS 6.
I don't know how to access the BIOS. I've tried several key
combinations, even held down as many keys as possible during
boot-up, but nothing's worked.
When the machine is turned on, there's first a screen with
"AMBRA" at the top and three check-marks appearing down a
list during a short diagnostic, then that screen goes away
and DOS text is visible during the rest of the boot-up.
Pressing any keys at all, during this whole process, only
gets the machine beeping.
Try F2, that worked for an "Blue Lightning" Ambra I had knocking about a few
years back, but you have to press it as soon as you turn it on, that had me
going in circles for a bit.
