The 286 had the ability to address 16 megs of memory by kicking the processor in to protected mode, but hardly anything was written in PM back then. What you could do (and you might remember this) was to referece the first 64k of extended memory even though you were in real mode. You did this by opening the A20 gate and then using a segment register loaded with FFFF to address the memory. It was called the "High Memory Area" and you used to load himem.sys to do that and "Load DOS High." Coming back to you yet?  |
Remember the MFM drive / RLL controller combo to fake it into thinking the drive was bigger. Got that 40MB disk to look like 60 then put stacker on it and got about 85. It only crashed about once a month.
Ok Stop. The flash back are killing me. I'm going to have to go to bed and reboot.
