I have a Sharp PC-3000 which (I think) is identical except it only has 1MB
of RAM, and I don't have a RAM card. I'm assuming that other than that both
machines are the same... The trouble is that it has DOS loaded into the
ROM. The DOS and BIOS have been hacked to work with its weird hardware so
anything that even thinks about meddling with the hardware is dead already.
Minix-86 can't access the 2MB EMS becuase it'll be running in real mode so
it can't acess above the 1MB boundry, and their is little chance anyway
that the memory will be mapped like real EMS (It'll be emulated at the DOS
level). The ram disks are again filesystems at the DOS level but work
differently in hardware, they're memory mapped rather than block storage
devices. The processor isn't even a real 8088, it emulates the 8088
instruction set but I'm not sure how well. Considering everything, you're
probably wasting your time.
