I have found what I think are 2 typos/omissions in the Minix Manual for the Atari ST. I am not a unix expert, in any sense of the word, so if anyone can see that my corrections are incorrect, please post it. 1. In the section on using double-sided diskettes, at the bottom of page 10, after the file system is made on dd0, you need to mount it (at least that is the way it is done on p.9). After the last line on p.10, add the line # /etc/mount /dev/dd0 /user 2. In the section on How to use Minix ST, the method of creating a TOS compatible sector 0 on a minix floppy is unclear as to when this operation is allowed/required -- can I do this any time, or only immediately after the mkfs command is executed for that disk? Also, the two lines that begin with "# dd" in the middle of p.17 should have the phrase "count=1" appended at the end of the line. The current lines attempt to copy an entire floppy, not just the first 512 bytes. i.e. replace "# dd if=/dev/dd0 of=/tmp/sec0" with "# dd if=/dev/dd0 of=/tmp/sec0 count=1" --Patrick Simon mpsimon@phoenix.princeton.edu 11-12-88

So far I have not received my copy of the official version from Prentice-Hall, so I cannot tell whether something went wrong during reproduction. Anyway, the mount command must follow mkfs. >2.

You may do it anytime after the mkfs, and before use under TOS. MINIX will not use or modify sector 0, except mkfs clears it. >Also, the two lines that begin with >"# dd" in the middle of p.17 should have the phrase "count=1" appended at >the end of the line.

BOTH 'dd' lines on page 17 have to be fixed that way. Thanks for the warning. -- Johan W. Stevenson johan@pcg.philips.nl Philips Research

I have both the electronic and paper copies too. I was the one who printed the manual (I have more pixels than Johan) although he was the one who wrote it. I also have the P-H manual. Thus I am somewhat flummoxed by the fact that the mount is in the file and in my paper copy, but not in the printed manual. I suspect the problem has to do with the fact that it is on the bottom line of the page, and they probably have some kind of a mask for making a uniform margin. In any event, it is not there and it should be. If people have found more errors in the manual, please post them and Johan and I will try to get the manual fixed. Incidentally, the fact that Johan hasn't gotten his copy is noteworthy. (a) P-H has a contractual, legal, obligation to send each author 6 copies, and (b) I specifically called up the editor in charge and asked him to send Johan his copies. Conclusion: when they quote you 2 week delivery time and sometimes delivery in 3 days and sometimes in 4 months, they aren't being mean. They are just a big company, and big companies are often confused. Andy Tanenbaum (ast@cs.vu.nl)
