re: the problem of supporting a small root image on MINIX/ST. What I did was change the driver, and steal the minor number 6. After minor numbers 0-5 are set up from the boot block, I create minor 6, by letting it reference the last 512 blocks of partition 3. (And, of course, reduce the size of partition 3 by 512.) Now I can boot from 3,6 , and mount 3,3 as /usr. The reason for taking the back 512 blocks is that I first loaded 3,3 with /usr in order to make the change. Remember to use the -t in mkfs for the root, i.e. mkfs -t /dev/hd6 512 (any number will do, just remember only 512 blocks are real) I also changed fsmain, so it automatically tries 3,6 for the root, and if it fails then tries 2,0 and 3,3. ALSO, I am using a BMS 100, and having no problems at all. Howard C. Johnson ATT Bell Labs ...lzaz!hcj

I had to pull one little trick to set things up as I wanted. I have two Seagate ST-225's, and I want to use one for TOS, and the other for MINIX. I first recompiled the system so MINIX would understand about the second drive. No problems there. The problem was that I wanted a 1 meg partition for the root, and the rest (19 megs) to mount on /usr. But, the Berkeley partitioning program won't allow a partition larger than 16 megs. At least, it won't if you try to dial your partition size from the dialog box. However, if you add a line to bmsinit.dat to add a new default partition scheme, you can have a 1-19 set of partitions. I haven't been able to look at the partition table to be sure it was written correctly, but so far so good. So, I now have two 10 meg TOS partitions on one drive, and a 19 meg MINIX /usr partition on the other. I think I died and went to heaven. Now to apply all these fixes and new programs people have been posting. Thanks to you all. -- Gerry Wheeler Phone: (519)884-2251 Mortice Kern Systems Inc.
