Here is a format program for Minix running with the BOOT menue.
It's algorithm is derived from Aubrey McIntosh.
It creates only the sectors, no filesystem, so you must use mkfs to use the
disk under minix. (You also can make DOS filesystems by dd ing the data from
an empty dos disk: dd if=/dev/fd0 of=/dev/fd1 count=5 for 360 K )
It can handle all floppies except 1.44 M ( I don't know the gap_len).
The program is NOT tested on AT's !
Cdiffs for fsck are also included, different for 1.3 and 1.5
You will find further Information in USAGE

X *
X * VERSION
X * 1.0 15. 1. 1990
X *
X * USAGE
X * This program can be included to the standalone fsck.
X * compile with -DBIOS
X * link with fsck1.s fsck.c necio.c dma.c and format1.s
X * change fsck to make a call format(drive) when
X * 'f' is typed in the Minix boot menue
X * Only useful with -DBIOS:
X * with -DAUTO the program reads the model Byte and determines the
X * drive type.
X * with -DTWODRIVES you can choose the 2nd drive (not with AUTO )
X *
X * without -DBIOS you get a version intended for Minix, but
X * !!! It don't work !!!!
X * I'm assuming that you cannot use DMA if interrupting is disabled
X *
X * PROBLEMS
X * This program is slow. DOS - Format and the Format0 from aubrey McIntosh
X * (running under DOS) are about 4 times faster. I don't know why.
X * It seems that returning from DoSeek - immediate before the Head number
X * is printed - comes very late - about 1 sec after you heard
X * the head motion.
X *
X * FUTURE WORK NEEDED
X *
X * Recognize bad sectors !!
X * Add command line switches for:
X * 1) Drive type.
