I have a new 40Mbyte Supra hard disk drive for my Atari ST 1040. The machine is a few years old with TOS in ROM. MINIX ST 1.1 doesn't recognize the drive. I've tried several approaches includeing running MINIX from GEMDOS with MINIX.PRG and MINIX.IMG generated from the boot disk. I would guess I need a different hard disk device driver but I've no idea how I will do that. Please mail me if you've got this combination to work or if you are reasonable sure how to do it.

If you; Minix 1.1, as shipped expects to find a minix root partition at partition 2. " /* Get size of RAM disk by reading root file system's super block. * First read block 0 from the floppy. If this is a valid file system, use * it as the root image, otherwise try the hard disk (RAM_IMAGE). */ #ifdef ATARI_ST printf("Booting MINIX-ST 1.1. Copyright 1988 Prentice-Hall, Inc.\n"); printf("Insert ROOT diskette and hit RETURN (or specify bootdev) %c", 0); root_device = (dev_nr)getdev(); if (root_device == 0) #endif " So, It is assumed that you first boot MINIX from a floppy. At this point you can prepare a partion, 2 being preferred for minix. 3. You can test if you have basic communication with the HD, from MINIX, by reading section 0, which is the boot sector, and partition 1, which is (I assume) TOS. dd if=/dev/rhd0 > /tmp/hd0 should not fail. tos -d /dev/hd1 should print familiar information on TOS c:. If either or both FAIL, then you have INTERRUPT problems. 4. Remember TOS is polled IO, not INTERRUPT. You would never no if disk interrupts failed under TOS. MINIX only uses INTERRUPTS. Assuming that the 1040 is not bad (Try someone elses HD); its a Supra problem. 5. Supra had three vintages of Atari interfaces. OLD (Never would run MINIX), Medium (could run minix with a Supra supplied software change), and NEW (as in with fan, and DMA OUT connector) that did work. Howard C.

Did the MINIX newsgroup ever split into IBM & ATARI sections? Or, is it still one big deal? BTW, I just purchased a used MINIX package, I wonder if I could get it re-registered in MY name? What's the latest version, this one is 1.1. Walden's 'computer store' <here local> carries a hardcover version of the textbook tellin' me that there ISN'T a softbound version, this true?

True part: The generic version of `the book' on Minix, by A. S. Tanenbaum, only comes in hardcover (at least as far as I know). False part: There is a version of `the book' specific to the IBM PC which is in paperback. Check "Authors in Print" at your favorite local bookstore. I own both of these. I don't know if there are other books for other (non-PC) architectures. > >Ed June buggs@cup.portal.com <<<<----- this is all I know! Phil Miller pcm@iwarp.intel.com

Everything I've read about it makes it sound like a `teaching tool'. MINIX is a stand-alone OS. The two are unrelated. Phil Miller pcm@iwarp.intel.com

>MINIX is a stand-alone OS. >Phil Miller >pcm@iwarp.intel.com Otay, thanks. I've still got my on the book at the mall. It has a section on the 8086! Gee, I don't need that. Also NO where does even mention the Atari ST. Is there a newer release? One that even mentions the ST? Ed June

Very old Supra's wouldn't work. Likely never did. They screwed up interupts. Typical of supras with out fans. 2. A middle vintage would work with software timing fixes. Supra supplied a posted driver to fix. I may have this in an archive. Typical of supras with fan without chaining (I think!). 3. "Newer" ones worked. Remember, MINIX, like UNIX is interrupt driven, and if the supra controller generates extra or suppresses interrupts, MINIX dies. Also, I did an upgrade, which is in all the archives to allow you to access partitions 4-12 on the supra. Disclaimer. I don't have a Supra. And I am glad!
