Networks:NIC:Abit IS7-E and 3com 3c940 driver

[deathadder]

ive recently brought a p4 with the motherboard, the board is a Abit IS7-E, according to manual the onboard is a realtek rtl8139/810x fast ethernet nic, so i have been usin, as root ofcourse

'modprobe 8139too'

this produces the error message
/lib/modules/2.4.22/kernel/drivers/net/8139too.o.gz: init_modules: No such device
/lib/modules/2.4.22/kernel/drivers/net/8139too.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid 10 or IRQ parameters
/lib/modules/2.4.22/kernel/drivers/net/8139too.o.gz: insmod /lib/modules/2.4.22/kernel/drivers/net/8139too.o.gz failed
/lib/modules/2.4.22/kernel/drivers/net/8139too.o.gz: insmod 8139too failed

so i search G4L and here a bit i found some information, which has got me a bit confused :)

for instance i found that i can find out if slackware can see my nic at all by doing lspci -v, but this produces the confusin information


02:02.0 Ethernet Controllers: 3Com Corportation: Unknown device 1700 (rev 12)
Subsystem: Abit Computer Corp: Unknown device 100a
Flags: bus master, 66 Mhz, medium devsel. latency 32, IRQ 10
Memory at f8000000(32bit, non-prefetchable) [size = 16k]
I/O Ports at 9000 [size = 256]
Capabilities: [48] Power Management version 2
Capabilities: [50] Vital Product Data


this confuses me because as i can tell its sayin that it finds a 3Com card, or are they actually the same cards?

any suggestions or information about how to get this onboard RealTek RTL8139/810x :confused: to actually work

before i forget its a full install of slackware 9.1

[DMR]

They are definitely not the same chipset. Are you sure the mobo is revision E? Abit does use a 3com chipset on some versions of the IS7.

[deathadder]

im sure that it is a IS7-E, accordin to the motherboard manual the IS7, IS7-M/E all use the onboard Realtek RTL8139 lan while the IS7-G uses a 3Com card

thanks for the reply

[DMR]

Yes, the G version uses the 3com; just checking.

Run the following command and look for any lines pertaining to eth0; what model of NIC is listed there?:

dmesg

[deathadder]

thanks for the reply, but dmesg doesnt show any reference to eth0

[DMR]

Hmm,

Anything at all in there that makes reference to either a Realtek or 3com NIC or module?

[deathadder]

no nothin at all, i've attached the output from dmesg, but i cant see anything that makes reference to Realtek or 3Com

[DMR]

There's probably nothing there because the module isn't loading and the card isn't initializing.

Here's the odd thing- from lspci you got:
"Unknown device 1700 (rev 12)"

Well, "device 1700 rev 12" is the correct device ID for 3com's 3c940 gigabit NIC. You really might want to pop the case and had have a look at the motherboard...

If you do have the 3com, it will use either the sk98lin or 3c2000 driver.

[deathadder]

ok i think this needs to be said, sometimes motherboard manufactuers change what they put on their motherboards, without updating the manuals that come with them, so for the latest information about your board check their website or look at the board

DMR your correct, it is a 3Com card, found the chip on the board when i opened it up, sorry for any misleadin info ive given you, i was only takin reference from the manual i got with the new board, the information i got from the NIC chip is:

3Com
Marvell
940-MV00
40-0779-000
FB22861 4
0313 BOP

also modprobe 3c2000 produced the error, Module cann't be located while modprobe sk98lin produced, the same error message as i first posted

/lib/modules/2.4.22/kernel/drivers/net/sk98lin.o.gz: init_modules: No such device
/lib/modules/2.4.22/kernel/drivers/net/sk98lin.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid 10 or IRQ parameters
/lib/modules/2.4.22/kernel/drivers/net/sk98lin.o.gz: insmod /lib/modules/2.4.22/kernel/drivers/net/sk98lin.o.gz failed
/lib/modules/2.4.22/kernel/drivers/net/sk98lin.o.gz: insmod sk98lin failed

They've moved to the faster 3com chip (which they were using in the "G" version of that motherboard), but haven't updated their literature.

1. Turn off Plug-N-Play OS support in your BIOS if you haven't already. BIOS PNP is a chief culprit when it comes to resource conflicts in Linux.

2. What is the output from the following 2 commands?:

less /proc/interrupts
less /proc/ioports

[adikgede]

Did you try "modprobe \*" yet?

[deathadder]

DMR:
I've disabled all PnP in the BIOS, also ran the two commands you said produced the following output

as you can see there 3Com Corporation there :), i couldnt find the 3c2000 drivers on the 3Com site, im about to G4L to find a d/

adikgede
tried it and nothing happened :( thanks for the suggestion though if youve got any other i'd love to hear em

thanks for your help so far DMR and adikgede

EDIT:
found a download for 3c2000 getting it at the moment, i'll repost when ive installed it

[DMR]

Yup, that's the 3com NIC at base address 9000, although I don't see it listed at IRQ 10 as lspci -v reported in your first post. :confused:

Well, let's see what happens with the 3c2000 driver....

[deathadder]

thanks so much for your help DMR, finally got the nic up and running in the end i had to go to the 3com site download a windows exe, install it, copy a folder called linux from the install dir, untar the 3c2000.tar.gz file there change the dir do a make, make load then ifconfig eth0 up, only after all that did the bloody thing work :)

once again thanks for the help

[DMR]

Great.

It sounds like you had to jump through a hell of a lot hoops to get there, but if it worked in the end, it was worth it. :D

By the way, while I was doing more research on your problem I found that there are some "weirdnesses" with certain versions of the sk98lin driver and your particular card. Apparently you can get the right driver from Asus' website, but since the 3c2000 driver is working for you I wouldn't muck with it.

Oh, and as far as your appreciation for the help goes- thanks, it's the only pay we get around here! ;)
