I used to run four (5.25") drives with no

laptop also had a provision to connect it to a PC's external drive
connector and you could then access the Multispeed's two 720k 3.5" disks as
the 3rd and 4th drive on the PC. I made a cable to connect the Multispeed
to the PC but I loaned it and all my NEC Multispeed manuals to one of the
members of this list and he never returned them. In both cases, I had to
add a line or two in the Config.sys file to make DOS recognize the 3rd and
4th drives.
If the motherboard switches (or CMOS in >= AT) are set for 2 drives,
then:
DEVICE = DRIVER.SYS /D:2 /F:2
DEVICE = DRIVER.SYS /D:3 /F:2
If the switches are set for 4 drives, then you could still use DRIVER.SYS
and access the drives as F: and G:,
Or use DRIVPARM, with /F:2
NOTE: DRIVPARM is present in both MS-DOS and PC-DOS, but UNDOCUMENTED in
PC-DOS, and is incompatible with the real IBM BIOS, although it will work
with almost all aftermarket BIOS's.
