View Full Version : Where Can I Find the Original IBM BIOS Listing?

20 years ago I lost the listing of BIOS from the IBM PC Technical Manual and it has irritated me ever since.

Anyone know where I can find it on the web or get a copy of the listing or buy the Tech Manual?

I have a (Xerox copy) Tech Manual somewhere, I'll look it up for ya.

The IBM PCjr Technical Reference Manual is online here:


(This is a zipped PDF.) It has the BIOS listings for the PCjr, which might not be quite what you need.
