Booting old PC with SD Card

A Need created a concept of no Commercial Value. I was unable to revive my Pentium from the Nineties, the FDD drives have gone bad, those i am able to get from some salvage computer shops are not working. 1.2 and 1.44 both, it may be FDD controller.

I have all the various boot floppies and software from 1990 onward and have made images also on CDROM.

If there was a SD Card interface for the Plugin Slots and an update for the Award Bios to boot from the SD card, i could get this going.

The HardDisk sizes needed are not available even in the salvage.

The External Pipeline cache also keeps popping out. The heatsink fan gone bad. But the things starts up and you can tweak only the Bios.
