I finally got some time to work with my 5150 and finish the dip switch configurations. I'm a bit confused though about one item.
According to minuszerodegrees, the section labeled "Switches 5 and 6 states the following:
On Switch Block 1, the one closest to the center of the mother board... And the part that is confusing me is that according to the table below, switches 5 and 6 appear to be set to the "On" position for an EGA video card. But right after that there is a sentence that states: ON/ON setting is only applicable to the 10/27/82 dated BIOS revision.
My computer is a revision 2 5150 PC. I'm not sure which BIOS version it contains. So what do I set switches 5 and 6 to?
5=OFF, 6=OFF: MDA (monochrome)
5=OFF, 6=ON : CGA, at 40 column by 25 line mode
5=ON , 6=OFF: CGA, at 80 column by 25 line mode
5=ON , 6=ON: Cards with a BIOS expansion ROM (e.g. EGA / PGA / VGA)
ON/ON setting is only applicable to the 10/27/82 dated BIOS revision.
As always; many thanks.
