Hello netters. I have a strange problem using st-minix, and that is that the system hangs up VERY often. Sometimes the system hangs immediately after loading the minix.img, whithout getting any chance to login at all ! This might happen 10-20 times in a row, and then suddenly the system will work for hours (and weeks). I can't seem to figure out any reason why this happpens at all, since nothing similar ever happens while running TOS. I`ve tried compiling the GNUkernel (which was a pain in the ... when the system started to hang...) but the same thing happened with this kernel. Right now I'm desperate, because I haven't been able to use the system for weeks, and I'm curious to see whether minix 1.5.10 will work any better. (Got the sources downloaded and all...) If i manage to login at all, the system usually hangs up after 5-10 minutes. I've tried recompiling my original sources for commands, kernel, and libraries but nothing seems to be working any better than the other. My hardware is a Mega-ST 2, whith a Megafile 60. (It also hangs up if I disconnect the hard-disk, so that is definetly NOT the reason). At first I didn't have a blitter, and when I finally got one, nothing was changed. I use (american) TOS 1.4, but originally had Swedish TOS 1.2 that didn't work either. Sometimes I get the kernel-panic message '*task got message from -1' when the system hangs, but usually I see no error message at all. Any hint to get rid of this uglyness is very much appreciated.

seems that something very basic went wrong.... did you CAREFULLY convert sendrec.s etc. to GNU syntax? C.v.W.

TOS (like MS/DOS) is polled not interrupt driven. MINIX ( like UNIX(r) ) is interrupt driven. You likely have a problem in either the interrupt handler (MMU and GPIB) or and interrupt generator (DMA, ACIA). These problems would normally not be seen under TOS. DMA interrupts are never used by TOS. Try reseating all of the chips, particularly the square ones (CAREFULLY). This solves many problems. Howard C.

Something which should be done, if you pull out your chips is: CLEAN all those pins with some sort of 'isprpyl alcohol' you'll wonder how much dirt is on those Pins and the sockets.. Ihad one a nearly related Problem, which i first tried to ix with cleaning the chips, that's how a got to this Informatione, at the end a fixed the Problem by pushing my ramextension(512k) will hard into the shifter socket.. So just Try to do the easy things first before unsoldering something.. Or write some test programs, which will test the severavb Interupsources in the ST...

Just to keep things tidy, that should be 'isopropyl alcohol', often sold as rubbing alcohol. The name is a chemical one indicating that is is an isomer (alternate form) of an alcohol with 3 carbon atoms. David
