[comp.unix.wizards] Formatting AT&T diskettes in ms-dos box

Sorry to repost but we seem to have some kind of censorship over here..

My original question was about formatting 720K 5 1/4 diskettes in a
PC in a way that those diskettes are acceptable for use in a AT&T 3b2 system.

DOS format does not work (the command works but the target system does
not accept even the low-level format).

Program exampel (MSC ASM) would be appreciated, komments about interleave
intersector gap for 3b2 diskettes also.

  If you have correctly installed DRIVER.SYS and formatted with the
correct options on DOS format you will be able to generate a 720k floppy
on an AT (1.2MB) type drive. Since various vendors hack their drivers
and format commands I can't give you the correct incantation for YOUR
machine.

  I have seen DOS gurus do this on Dell MS-DOS and PC-DOS with vendor
supplied software, and have been able to read the disks as 720k on
Xenix. Is the 3B2 format the same? The DOS stuff produces 80 tracks, 9
sectors of 512 bytes.

Congruent Technologies in Richardson, TX has a software package
that will allow a 3b2 to process the standard 360K DOS diskettes.
I don't know what it costs, or how well it works. But I have used
their memory products and the quality has been good.
