I'm working towards getting my Compaq Portable 386 up and running, but found something weird that I don't quite understand.
My system reports 2048kb ram on bootup and for the 'mem' command. It has 4 sticks of 512kb ram installed. According to the jumper settings, it also has 640kb ram onboard.
I had asked an eBay seller to tell me how much ram their Portable 386 had and they said '2688kb' which I thought was a really weird number until I realized that was 2048kb + 640kb.
After thinking about it, I don't remember any 386 or newer systems adding in that extra 640kb, so what's going on here? If my system has it, why doesn't it allow it to be used?
As an aside, if anyone has the 4mb expansion ram cards for sale/trade, please PM me
