[K12OSN] K12LTSP missing some important stuff for our school purposes

OK, this is what came up:

starting syslogd
Running Sound Server
es1371: version v0.32 time 19:56:37 Jul  4 2006
ACPI: PCI Interrupt 0000:00:0e.0[A] -> Link [LNKC] -> GSI 10 (level, low)
-> IRQ 10
es1371: found chip, vendor id 0x1274 device id 0x5880 revision 0x02
es1371: found es1371, rev 2 at io 0xb800 irq 10
ac97_codec: AC97 Audio codec, id: 0x8384:0x7609 (SigmaTel STAC9721/23)
- accepting connections on port 16001
/dev/dsp: Device or resource busy
Starting Ibuscd...

...etc.
... btw, where is this log (for connecting clients) kept?

So it looks like there was a resource conflict or something.

So I checked in the bios and slots 3 (NIC) and 6 (sound card) shared the
same resourced. I switched the sound card to a different slot. Now I'm not
getting the "Device or resource busy" error, but still no sound.

I'm using esd and gnome desktop.

And as I mentioned this same system boots happily with sound under
DamnSmallLinux.

Regards,
Tom Wolfe
