Just for fun, I tried to boot FreeBSD 2.2.2 from within the VirtualPC emulator for MacOS, which claims to simulate a full Intel Pentium PC at the hardware level. It can run unmodified version of Windows 95, NT, OS/2, and NextStep, and so I assumed it wouldn't have much trouble with FreeBSD. Unfortunately, immediately after loading the kernel, FreeBSD panicked with this error: Fatal trap 1: privileged instruction fault while in kernel mode instruction ptr = 0x8:0xf01b99aa stack ptr = 0x10:0xefbfff38 frame ptr = 0x10:0xefbfff50 code segment = base 0x0, limit 0xfffff type 0x1b = DPL 0, pres 1, def 32 1, grant process eflags = IOPL = 0 current process = 0 () interrupt mask = net tty bio panic: privileged instruction fault Obviously, this is a bug in Connectix's CPU emulator. But I'm curious if anyone could give any information off-hand as to what they might be doing wrong that would trigger such an error from the FreeBSD kernel. Thanks, Jake Hamby
