When booting from floppy on these machines, the option is to "Boot FreeBSD with ACPI enabled", while on other machines it says "Boot FreeBSD with ACPI disabled". Looks like this is from beastie.4th. We tried both options and it still panics when it is extracting base (ie. you can partition, newfs, etc... using sysinstall). It gets about 2% of the way through extracting base. So, tried going to the command line from the loader menu and unloaded all loaded modules, and disabled further loading of ACPI, then continued booting. The kernel is loaded into memory, we get the "Too many holes in physical memory" message and it panics immediately after the copyright message with a: Fatal Trap 12: page fault while in kernel mode fault virtual address: 0xb5 fault code = supervisoer read, page not present ..... some other guff.... panic: page fault uptime: 1s This is the error condition we experienced with our RNA before bumping up the phys_avail[] in machdep.c I am planning to ditch all of these old Pentium machines because they are too much of a problem. I'll keep one for a little longer if you like to figure out what is going on. Paul.
