I'm installing Mandrake 6.0 on a Compaq Presario 4504, and I'm running
into two problems which are rather distressing. In short, it won't
communicate with the NIC or the modem. First the NIC problem. At
system boot, it says it's bringing up eth0, and it gives a green "OK"
indicating that this was completed successfully. Other services
(apache, samba, etc.) also start normally. However, when I run
ifconfig, the NIC isn't there. It's a PCI NE2000 clone based on a
Realtek chipset. /var/log/messages shows
Sep 17 12:39:54 ffj network: Bringing up interface eth0 succeeded
Sep 17 12:39:57 ffj kernel: eth0: PCI NE2000 found at 0xfca0, IRQ 0, \
00:60:67:4A:03:E5.
But, when I try running "ifup eth0", I get
SIOCSIFFLAGS: Resource temporarily unavailable
SIOCADDRT: Network is down
I also tried it with a Linksys tulip-based card, with almost identical
results. I see that the kernel reports irq0, which I suspect may be a
problem, but I don't know what to do about it. Other than that, I don't
have a clue. What else should I check?
Second problem, the modem. It's an ISA, hardware modem with DIP
switches and jumpers to select resource settings, or it can also be
configured for PnP. First, I tried it PnP, since I didn't want to go
digging for the manual to find how to set the switches. pnpdump found
it just fine, so I edited isapnp.conf to select com3, io 3e8, irq 5, and
ran isapnp. It responded with a fatal error allocating 8 bytes of io at
that address. Per /proc/ioports, 3e8 was free, and /proc/interrupts
indicated that irq 5 was also free. Isapnp gave the same error with
every other selection I tried.
Thus foiled, I found the manual, and set the modem to com2, irq 3. The
system saw the com port when it booted, but it didn't work properly. I
could open minicom, but the modem took about 20 seconds to respond to
"AT." I tried setting the modem to com3, irq 5, again using the
switches, and had the same result. Normally, I've found that this comes
from an incorrect irq specification, but that wasn't the case here
(setserial reported correct information both times). I haven't yet
tried adding my external modem on the built-in com port. Any ideas on
this one?
Any help would be much appreciated.
