[comp.os.minix] Reading /dev/dosX

hgv@daphne.network.com (Harry G. Varnis) (04/23/91)

I've been looking at why I can "dosread" some of the files on my DOS
partition but not others.

It seems that if I lseek /dev/dosC with offsets <= 44135423
and then try to read a byte it works.  If the offset is greater
the read returns zero (end of file?).

44135423 == 0x2a173ff. Does anyone know what's going on here?

BTW, its DOS 4.01 and the partition is ~120M.  I'm running MINIX-386.

Also, the linkage between FS and the disk driver for char special
devices isn't clear at all to me.  Any quick hints about where to
look?

Thank loads.
