I used MINIX 1.2 (PH) 100% successfully on my AMSTRAD PC1512 and a 20 MByte
Filecard from DYSAN. One partition 15 MByte for DOS and 5 MByte for MINIX.
In December 89 I successfully moved MINIX 1.2 to my new 386-SX on it's own
drive with a seperate partition of 18 MByte ( /dev/hd7 ). But I had to use
the original 1.2 AT-boot-diskette. Recompiling the 1.2 kernel with either
the at_wini.c AND the xt_wini.c leads booting to hang during mount of /usr
in /etc/rc .
Also in December 89 I received the 1.3 upgrade kit and successfully
compiled the 1.3 kernel but the 1.3 boot diskette does not mount too. I
tried that boot-diskette on another 286-AT and it DID run !!! On my 386-SX
the problem seems to be the same as with the 1.2 kernel. I found that the
original 1.2 kernel cannot be reproduced with the original sources as
delivered on the 1.2 AT-disks.
The original 1.2 binary /usr/tools/kernel is 25010 Bytes long, all
recompiled 1.2 versions are shorter (eg. with at_wini.c 23630 Bytes).
Pressing F1 with the 1.3 kernel will display the following picture:
proc ... flag ... recv command
TTY 0
PRINTR 8 ANY
WINCHE 8 IDLE
FLOPPY 8 ANY
:: : :
SYS 8 ANY
IDLE 0
MM 8 ANY
FS C WINCHE
INIT 8 MM
3 8 MM /bin/sh
4 8 FS /etc/mount
Trying 'h7' (check file system on hd-partition) on the boot-menu will 100%
work with the 1.2 kernel and with the 1.3 kernel !!!
What's going wrong, what should I do? The speed of the 386 should not be
the problem, I switched it to 8 MHz with the same result. Should I buy
another equipment or forget MINIX?
Equipment: 386-SX (HIGHSCREEN from VOBIS) running at 16 MHZ, NEAT-Chips, 1
MByte RAM, two HD-drives, each 31 MBytes, Controller: Western Digital
WD1003V-SR2 (RLL 2.7).
