Hi Michael, Hans, Glenn;
FWIW, on my machine (with shadrow ram enabled) a test with DOS 6.22 MEM /C
shows only 64k reserved - I'm sure with a little effort I could get that to
zero. My boot screen (Under the AMI bios boot report box) shows:
256k cache, 128k shadow ram.
That test was done using QEMM 8.01 as memory manager as it happened to be on
the boot disk. I normally use QEMM 5.12 these days as it leaves a heck of a
lot more memory for me.
