Hello everybody, I have just got hold of my MINIX disks at long last, and have a small (well, not so small, really) problem with the hard disk task. Everything works perfectly well with the floppies, however after setting up a hard disk partition according to the instructions, and making a file system on it, things start to go wrong. I created all the necessary directories to duplicate the /usr diskette, no problem. I then copied all the /usr/bin files to the bin directory on the hard disk, apparently no problem. However, when I came to execute *some* of the files off the hard disk, I got streams of "Unexpected trap: vector < 16" messages. After a while I discovered that the original file (in this case /usr/bin/wc) and the copy on the hard disk were not the same !!! In fact, one block (1k) in the middle of the file was completely corrupt. Re-copying the file solved the problem. Moving the MINIX partition from the 'end' of the disk (an area previously unused, and therefore possibly suspect) to the beginning (an area obviously OK) disn't make any difference. Nor did switching between 10MHz and 6MHz. I realise that I don't have a 'standard' disk controller (this one appears to be Japanese, made by a company called NCL), but I do have a standard (ie not specific to that disk controller/drive combination) PHOENIX BIOS, so it must be standard enough for that. I am currently engaged in comparing the AT_WINI.C listing with the IBM AT BIOS listing to see if I can find any differences, but if anybody knows of a cure, or has simply experienced the same problem I would be glad to hear from you.

In-Reply-To: <304@louie.udel.EDU> I had a simular problem. Have you applied any of the patches to at_wini.c supplied on the net? I fixed up the command[6] line, and the problem went away. j.b.
