Hello Netties!
This question goes to Atari-Minix users:
I got a second Harddisk for my Atari (Very old, very slow). I reserved two
Partitions (each ~16MB) for Minix. Now my Question:
Do I have to change/recompile the kernel etc.(Where?) to use this drive?
(It is installed as DMA 0/lun 1)? Or is there any better way?
Hope someone could help me,
Ciao,

The default set up of minix-st 1.50.10#3 looks after two drives in unit 0, and the first drive in unit 1. Please read the source code for details.

Hi netters,
I just tried to bring up minix with a second hard disk, too and encountered
lots of problems. Perhaps there's so. out there who could help me.
My first drive is an ATARI SH205, the second one a SQ555, with removable
media.
After installing the second drive (G-DATA SCSI-Controller) I tried to boot
up MINIX ST 1.5 patchlevel 3 which worked fine until then. The only answer
I got was sig=11 pid=0 ....
Then I tried to boot up ST 1.5 orig from Disk, it worked fine and I even
could access my (first) hard disk. So I took another step:
I tried to boot just that minix from hard-disk: sig=10 pid=0.
After further research I found NR_DRIVES in config.h was set to 3 for the
new (patchlevel 3) kernel.
So perhaps some kind soul out there has encountered similar problems and
found a fix for them.
And it would be nice if someone could explain me how major and minor
device no. have to be set ?
Since I have 2 controllers now, does NR_DRIVES have to be 2 or 4 or
what else ?
Another one: i read something about the hooks for removable media in
the LOG file. Are there just the hooks or is it implemented ?
Thanks in advance for any answers.

Yes. The standard number should be 1, but my system has three drives, so I accidently send out the wrong version. >So perhaps some kind soul out there has encountered similar problems and >found a fix for them. Can you use both disks under tos?? Are your device numbers right. Also there is a fix out on patch 3. Have you tried that? I think you will need it, but I'm not 100% sure any more. >And it would be nice if someone could explain me how major and minor >device no. have to be set ? See the comment in stwini.c >Since I have 2 controllers now, does NR_DRIVES have to be 2 or 4 or >what else ? No. 3 is fine. drive 1 = scsi 0 lun 0 drive 2 = scsi 0 lun 1 drive 3 = scsi 1 lun 0 etc. You are/you should have one drive configured as scsi 0 lun 0 and the other one as scsi 1 lun 0 (if they have their own controllers, if you have two disks on one controller then they are lun 0 and lun 1). >Another one: i read something about the hooks for removable media in >the LOG file. Are there just the hooks or is it implemented ? It should work. However, I do not have any removable media to test this on. Your comments are appreciated. >Thanks in advance for any answers.

Hi all, During the weekend, I had time to get the Disk up and running - at least partially. First I discovered, that it was all my mistake: I had modi- fied config.h to have the root file system on /dev/hd3, but had it on /dev/hd2 after partitioning and restoring. So Minix couldn't find its root file system and crashed. I fixed that and went on to try the 2nd drive. I just mknod'ed minor no. 35 and 36 and everything went fine, until - until I tried to readall -t /dev/newdisk. Afterwards Minix didn't recognize any of my HD's. This still is the case: I can mount and use the SQ555, but I can't use readall or read from the plain device. By the way, until now I didn't try to remove any media, while minix was running, I'm going to test that later.

Do you mean there is a fix to patchlevel 3 which I need ?? ! This space intentionally Martin Sckopke (X913@DMAFHT1) ! ! left blank.
