I just tried going through the long floppy install on another one of these machines I have in my home test rack (they don't boot from the cdrom anymore), but stopped trying when the single IBM SCSI disk attached to an Adaptec controller was detected as da0, da1, da2, da3, da4 and da5 !

We used ULE on 5.4 because it used less space on the floppy image and there was really only one process doing much on the machine, but I did some playing this afternoon and see that on 6.0 ULE and 4BSD use up the same amount of space, so I am changing it back to 4BSD. I am not so stretched for space on the floppy anymore after getting rid of the second GLOBAL_OFFSET_TABLE text.

6.0 Release - Pentium install panic and some questions
Hi, we are having a number of issues with 6.0-Release. Our setup: We have ~40 machines in a development test environment, ranging from P5/150Mhz/32M ram/IDE, PII Celerons, P3, P4, single and dual processor setups. Issue 1: Can't install on a Pentium P5 class machine: The install panics when installing the base stuff. No useful messages are displayed accept the panic: page fault and rebooting in 15 seconds. The machines are 10 year old DEC Pentiums, 32 to 64M ram, IDE disks, etc. We have four of these in our test environment and appear to install and run FreeBSD-5.4 fine. Issue 2: phys_avail[] array too small in i386/machdep.c P5 boxes ?? We have something which we call a Remote Network Appliance (RNA), which is basically a boot floppy with lots of stuff squeezed on it. The RNA uses a cut down kernel config (ie. no kernel source modifications), various other inhouse programs (eg. init/inetd/telnetd replacements), built into a 1Mbyte MD root. We have no problems using everything up until a 5.4-stable kernel but have various problems with 6.0-release. When using 6.0, we get the following messages: Overlapping or non-montonic memory region, ignoring second region ... Too many holes in the physical address space, giving up ... Fatel trap 12: page fault while in kernel mode ... panic Did a bit of searching and found that in Dragonfly phys_avail[] in i386/machdep.c has been bumped up because it is too small. Looking at 6.0 machdep.c, looks like new dcons stuff has been added to it, and it blocks out some physical memory to use. Not sure if that has anything to do with it. From my understanding, phys_avail[10] gives you room for four physical available address ranges (ie. 4 * start/end pair entries and null terminated). I bumped the number up to 12 (ie. gives me five address ranges) and we are off and going. 6.0 now boots on all our Pentium machines, but... on 5.4-stable we got: physical memory: 67108864 avail memory:56156160 on 6.0 with phys_avail[12] we got: physical memory: 67108864 avail memory:63299584 more available memory for some reason ! Hmmm. On most of our machines, when booting in verbose mode, the 5.4 kernel reports three phys_avail segments, but the Pentium boxes report four. On the patched 6.0, the Pentiums report five segments. Unfortunately, the machine panics on Pentium machines when stress testing it (ie. by making it run out of memory). On 5.4-stable it would just kill user processes, under 6.0 it kills a few processes but quickly panics with a page not present error. At least 6.0 now boots and runs on a Pentium, whereas the standard install panics. I can't get a dump of the RNA floppy panic because it has no swap or disk to write to, and there isn't enough room on the floppy to build a kernel with debugging stuff. So, my question is... is it OK to bump phys_avail from 10 to 12 ?? or do we just ditch the Pentium as a supported platform ? Dragonfly have bumped it to 22, giving 10 segments. The only other change we do is compile the kernel and world with -Os and -funit-at-a-time to reduce the resulting binary sizes. fyi, A copy of the floppy image is at: http://www.statseeker.com/downloads/lanstat_fbsd60.bin It also contains our realtime Statistical LAN Analyser.
