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?
