Problems in getting Minix 1.2 onto a 40meg hard disk with DTC-5150crh controlle
t.

Equipment Configuration: DTK-10Mhz, Herk Graphics, DTC-5150CRH controller and S
T-251
40 Meg. hadr disk.

Disk setup: 2 partitions, 20Meg each. 4 sectors per cluster.

Problem: Minix can only find the first partition (/dev/hd1). Limited to
10,300 blocks (approx). will not write to /dev/hd2. With all partitions
removed, will only access /dev/hd0 - still limited to 10,300 blocks.

wini.c points to 0x1c6 for disk partition information - it is not there -
text messages from the dos boot header.

fsck - has been fixed for 6 disk heads. does work - part of the time.

A fix was reported by jel@cheviot.newcastle.ac.uk and werner@nikhefk.uucp
Cannot locate these postings.

Any suggestions where to start looking or what has to be done to get
this system to fly?

Al McIntosh, usadacs@simtel20.army.arpa
Thanks.
