Hello again, the problem is solved. Many thanks to all people who answered to my posting. Following Steve's suggestions I noticed carefully the amount of memory tested by the BIOS. In my case this is 130496 kB which is smaller than the physical memory size by the same amount Steve reports (576 kB). After putting MAXMEM=130496 into the kernel configuration file the problem did not show up again (Jerry's solution of subtracting 1 MB should therefore also work as well as my solution of leaving out 32 MB). I think that such a difference between the physical size of memory and the really available size is not uncommon. I would think that this is caused by the fact that some parts of the address space are mapped to ROM and devices thereby hiding some parts of the RAM. What is really wrong is that (without a MAXMEM statement) the size of the usable RAM is not correctly determined by FreeBSD. Since this obviously works on other machines (also hiding a part of the RAM) I would think of a BIOS flaw.
