I am running two PC's with DSL. First one is a somewhat newer computer: AMD 1.4GHz. One this CPU, the network gets autoconfigered fine and I access internet through the router.

The problem is with my older computer: Pentium 100, 40MB ram

The network card is ISA and plug and play is disabled.
The card gets auto-config fine as NE2000.

For some unknown reason, I am not able to use DHCP. when I run netcardconfig and try to activate DHCP broadcast, it returns Operation failed.
However, I can set a fixed ip (192.168.0.3), and from my AMD, I can add this ip to the router. The router recognizes it, it finds my old pentiums HWaddr (00:E0:29:...)

But even with this link formed, I am not able to access internet, neither am I able to pign my router from the box.

Help would be appreciated.
Thanks

Perhaps you network mask and gateway are configured incorrectly on your Penium 100 box.

The usual netmask for a local router is

255.255.255.0

which means that your local computer network address range is:

192.168.0.x where x = 1 through 254

For all non-local traffic (Internet) is sent to your gateway address, which is your router's locad ip address, is usually:

192.168.0.1

or sometimes

192.168.0.254

Hopefully, this will help you to be able to send outgoing packets from your pentium box and have them go to the right place.

This is my router status:

I.P. Address: 192.168.0.1
Network Mask: 255.255.255.0
DHCP Server: ON
DHCP Start IP Address: 192.168.0.2
DHCP Finish IP Address: 192.168.0.51

I know I have my settings right because I m able to assign any fixed ip with my AMD box through netcardconfig.

Is it normal that my isa card is not able to use DHCP?

I<ve used this network card under win95 no problems.

DHCP is a protocol. It should not be limited by your choice of hardware.

From your description, you should be able to assign the following in netcardconfig:

static ip address: 192.168.0.52
network mask: 255.255.255.0
gateway: 192.168.0.1

and it should work.

Of course DHCP should also work too so I am scratching my head here.

Also, instead of using the netcardconfig from the menu, try this. Open an xterminal window and type:

sudo su
modprobe ne
netcardconfig
exit
exit

Also, booting with:

dsl noapic

might help too.

Thanks, but these two solutions did not work for me.

I am still trying to solve my network progblem.

I think I came across this problem too in one computer where I tried Knoppix. It has an ISA card that gets detected as NE2000. The solution lies in running some setup program in MS-DOS mode in order to permanently set something on the ISA card itself. If you still have the installation floppy disk for this card, you should find it there. The manual will tell you that you may not need to do this if you run Windows 9x because it was set to run with Windows 9x by default.

I found the setup software somewhere on the net. It has been 2 years so I forgot what/where it is.

I opened up my cpu to check the net card. it is SMC1660T-50.

I found this on SMC's website: < http://www.smc.com/index.c....=0&os=0 >

and also this driver wich looks the same + pdf manual: < http://www.network-drivers.com/drivers/147/147027.htm >

I tried to load the installataion under MS-DOS to mess with the card's configuration, but I keep getting : please insert driver disk in the installation procedure.

There is also a linux folder in the driver disk, but I don't know how to use this one.

Is there another driver I could load under DSL that might work for my cad?

Guest: do you remember what needed to be changed on the card?

Posted by tedlegrand on June 07 2005,00:06

I was able to access the card's configuration with setup166.exe

The current configuration was set to plug & play. I changed it to jumperless (NE2000).
other unchanged configuration:
Medium Type: Auto-detect
Full-Duplex: Disabled
I/O Base: 300H
Interrupt: 3 (IRQ)
Boot ROM: Disabled

After changing the configuration to jumperless, the card was no longer auto-config at boot-up.
mprobe ne could not load the drivers also

What are my options?

Thanks for all of your help.

I was finally able to get my network running using information on this thread at this point. < http://damnsmalllinux.org/cgi-bin....9;st=10 >

after setting the card to jumperless, modprobe ne did not work, but

modprobe ne irq=3 io=0x300 did the trick.

Conclusion:

For isa network cards to work under DSL:

1. set your card to jumperless mode (dos utility for your card or jumpers)
2. take note of I/O and irq settings
3. enter command line modprobe ne irq=? io=0x???
4. run netcardconfig.
