Does anybody know if DOSREAD, DOSWRITE and DOSDIR on Minix 1.2
can read and write 3 1/2" MSDOS disks?. DOSREAD etc on 1.1
works out the disk's "dimensions" via the "Media Descriptor"
byte in the first entry of the FAT table. It will thus
confuse 720k disks with 1.2M. I've just re-written it to use
the info in the boot sector - so it now copes with virtually
ANY format. I'll post it to the group (or wherever) if
Minix 1.2's hasn't been "updated". It's also got a lot of other
mods to allow it to run on my Applix (don't worry, you wont
have heard of it) under it's OS (which can't open /dev/fd?
files), but these are all #ifdef'd, so that's ok. Oh yeah;
another thing:- can anyone explain why DOSREAD doesnt just
do calls to "printf" etc etc. Why does it have all that
"print_string" stuff?. why not use printf directly? (my
modified version does - will it still work on Minix?).
