DSL Duck Does DHCP
A tip from Peter Skye
"If Mark's fiddling with his Tekram card finally got Hardware Manager to
see his printer, I'll bet your problems are because of your sound card,"
quacks The Duck, looking through my email.
"You nitwit," says I, "the sound card has nothing to do with my network
card! And get out of my email!"
So Mr. Quackers hops off the chair, stroddles over to the tall tower
wherein grinds the hardware, grabs the TidalWave 128 sound card with his
beak and gives it a yank. Out it slides, and El Ducko drops it on the
floor.
"The power's still on!" I shriek.
A quick peck on the Reset button and the machine reboots. We watch the
screen. No error messages. No shared IRQs. And DHCPMON reports a
valid IP address lease.
"See?" quacks The Quacker, who heads out the back door for the pool.
A quick review of the IRQ table shows why the machine now works. The
TidalWave 128 is an ISA PnP card and was always given two IRQs, 7 and 9
(probably one for sound and one for MIDI, though I'm not sure). For
some reason, this particular Award BIOS won't use all the other
available IRQs for the PCI PnP cards, and puts all of the PCI PnP's on
one single shared IRQ. But with the TidalWave gone, the IRQs are now
assigned as 9, 10, 11 and 12 (for the scsi, video, usb port and nic,
respectively).
Stupid Duck.
