Enought of this religious war about dosread.c. Back to work, or am I the only one having dosread failures. I can get it to read drive A floppy disk low density(360) and drive B floppy disk high density (1.2M), but it rejected drive C my MFM hard disk drive. Therefore I enabled the debug define and got for a printout: MINIX> dosdir -l c OEM = ^NP^N@^NX8 Bytes/sector = 35708 Sectors/cluster = 224 Number of Reserved Clusters = 35835 Number of FAT's = 240 Number of root-directory entries = 191 Total sectors in logical volume = 64638 Media descriptor = 0xB9 Number of sectors/FAT = 256 Sectors/track = 42483 Number of heads = 233 Number of hidden sectors = 47362 Bootblock magic number = 0xAA55 reserved != 1 Can't handle disk Robert R.

That's the problem I had too, but since my knowledge of DOS is near zero, as I have pointed out, could somebody who knows more please take a look at dosread. Andy Tanenbaum (ast@cs.vu.nl)
