Some questions:
1) Why did Microchannel fail so completely? From a user point of view it
seems quite nice.
Closed architecture?
2) Can MFM or IDE drives be used with an ESDI
controller, or do the drives
have to be ESDI drives?
And ESDI controller is for ESDI drives, just like an IDE controller is for
IDE drives.
3) Anybody know if the 486DX33 on the processor board
can be replaced with
an Overdrive chip to make it at least a 486/66; or, does IBM still run
their parts depot in Boulder for old machines?
I don't see why not. There might be a clocking issue with the IBM
motherboard, i.e. it won't let you set the clock rate like on standard PC
motherboards. I wouldn't know, not being a PS/2 expert.
3) I'm having some trouble with the P70.
Originally, it wouldn't boot at
all. I ran the diagnostics from the Reference Disk, and all tests were
passed. I re-ran the Auto Configuration with no errors. I installed PC-DOS
6.3, and formatted the built-in HD at the same time. Everything seems fine,
but the system won't boot from the hard drive alone. If I boot with a
floppy in the drive, I can access the HD and run programs off of it. But
without a floppy, nothing works. Any ideas?
Did you format the disk with the "transfer system" option? That would be:
format /s c:
You can transfer the system after the fact with the following command:
sys c:
