Ooooookedokee...
I just rebuilt my 4.2-release kernel to enable APM support so I can
power-down, and it works, but with a helluva strange effect. Pardon
me if this is a known problem, I'm somewhat of a newbie and not finding
anything about it, including in the 4.3 release notes.
After shutting down with shutdown -p, I get no video. But it's not
just a software problem; the motherboard gives its three long beeps
to indicate that the *video card* is not recognized by the BIOS. So
I power-cycle... same problem. I let it boot to FreeBSD, then do a
shutdown -r, and guess what? It comes back up with video, no more
ugly hardware beeps from the motherboard.
My system:
Microstar K7TPro2-A (MS-6330) motherboard
Award Module BIOS 6.00PG
STB Powergraph 64 (S3 Trio64V) PCI video card
boot message snippets:
FreeBSD 4.2-RELEASE #0: Fri May 4 11:14:49 PDT 2001
adam@npomail.amberbug.org:/usr/src/sys/compile/NPOMAIL
apm0: <APM BIOS> on motherboard
apm: found APM BIOS v1.2, connected at v1.2
pcib0: <Host to PCI bridge> on motherboard
pci0: <PCI bus> on pcib0
pcib2: <PCI to PCI bridge (vendor=1106 device=8305)> at device 1.0 on pci0
pci1: <PCI bus> on pcib2
vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0
sc0: <System console> at flags 0x100 on isa0
sc0: VGA <16 virtual consoles, flags=0x300>
(except of course when the video card isn't found, the vga line is absent)
And to summarize, the sequence is:
shutdown -p
<no video>
power cycle
<no video>
power cycle
<no video>
boot FreeBSD
shutdown -h
<video>
And from then on it's fine. So.... whassup with that?
Thanks!
adam
