Configuring the PS/2 requires booting a prepared floppy disk to do so to configure and store settings.
Most and easiest way is:
Floppy drive issues:
Have someone who is good with SMD repair replace these SMD capacitors and re-grease the stepper screw (particularly bearings) so screw can turn properly, have to watch it to make sure. I had one of PS/2 floppy drive that stepper screw not turning from grease turned into glue.
Restoration is mandatory as finding *correct* working parts such as floppy drives for PS/2 is expensive, like 100 dollars each these days and is not physical and electrically compatible. Different PS/2 models used different floppy drives interfaces even the bezel to match is different too!
eg: 55SX, 70, 80, 85, 95, 77 used different floppy interfaces pinout.
The PS/2 8580 is MCA slots, it is not anything you can use any cards. Has to be MCA cards.
The reason I said MCA SCSI card as it is most easiest way to go and still is costly.
But this performance performs well only on EGA, VGA DOS era games not such as Doom up to VGA and Windows 3.11 but no sound.
Sound card is expensive. Read expensive even the MCA snarker is more than 100 dollars.
In other words restoring any PS/2 computer with MCA bus is expensive and difficult to source parts other than SCSI.
I know this and had migrated away from PS/2 long ago to standard generic PCs parts even brand names like, HP, IBM (ISA, PCI), etc, Compaq is better way to go. I have not yet acquired any parts for my PS/2 70 for years and needs SCSI controller along with small SCSI hard drive to complete. But what good if I can't play without sound so it sits gathering dust.
Best fit all is build you own PC based on Pentium that runs 120, 133, 166 or 200MHz processor based on ATX form factor motherboard, 16MB or 32MB, non-sound blaster sound card, PCI S3 or cirrus logic video card, so you can use any ATX PSU and ATX case. This will cover widest range of DOS games from 1988 thru late 1990.
