ISA is clocked at 8.3MHz, PCI at 33MHz. ISA has more CPU overhead too.
This card is 10bT if I recall correctly, so it won't move more than
about 850KB/s. If you want 3MB/s you'll have to go 100bT which means
PCI.
Are you sure the slot is defective? My PCI slots 4&5 share an IRQ which
could cause weird behavior under some circumstances. Other boards that
have built-in SCSI, sound, etc are known to share IRQ's with particular
PCI slots.

Well folks, thanks very much for the suggestions. Adam, I'd love to implement
something like yours but I barely talked my wife into this rig so it's the
poper's net for now. Besides, Pacbell claims that they'll have ADSL for less
$ in my neihborhood (belive it when I see it) by Sept or Oct so mabey I'll
try that. All that aside, after a couple of weeks of serious experimentation
I finaly got both chanels to go, about 10 mins ago in fact. I'm posting my
results for any other poor letches such as I, but as with Linux results may
vary. Here goes:
This script worked under RH 5.2 with a 3Com impact IQ running firmware 3.0
and a standard 16550a uart on the motherboard
#!/bin/sh
pppd debug modem crtscts asyncmap 20A0000 defaultroute noipdefault lock \
user [myusername] connect 'chat -v "" ATs71=1s80=1 OK ATD[my_isp_number]
CONNECT"" ' \
/dev/[my_comm_port] 115200
The stuff in brackets needs to be changed to fit your individual needs.
Notice the AT init string, very important. s71=1 turns on async translation
in the TA and s80=1 turns on multilink PPP. In order for async to work you
must use the asyncmap option. The setting of 20A0000 worked well for me. Also
be certain to set up your /etc/ppp/pap-secrets file. Evidently MPPP only
works with PAP so use that only and omit your login info from the chat part
of the script. The user option in the script is what points to what line to
read in pap-secrets. Good luck to any of you attemting this little exercise,
it can be a real pain in the ass.

Francisco,
I think the first step is to see if linux thinks the ethernet card is
working. You can do this by typing:
% ifconfig
This should produce output reporting on the status of all interfaces
that are up. If you don't see "eth0" among them, then your interface
may simply need to be started up with the command:
% ifup eht0
then type "ifconfig" again. Now do you see eth0 anywhere?
Try this first. If it doesn't work, then post again, saying that you
tried this and that it didn't work. Then we'll try something else.
good luck!

Subject: Trouble with connections
Date: 31 May 1999 10:22:05 GMT
I have troubles with my connection to Internet. I have installed Rh 5.0 and
I have 2 3c509b combo NIC's. First at boot linux finds everything all right
and ping gives correct values when reaching beyond to default gateway. Then
after few minutes suddenly I can't get to the Internet anymore. connections
to my subnet works fine but not beyond the gateway. I think this is a linux
problem because when using WinNT everything works fine. So if anyone has any
hint or tips/tricks how to get this thing going please inform. Everything
useful is appreciated.

Yes and ISA does 16MB/sec (thats 16 megabytes per second) 10 base T is 10
Mega BITS a second>>>>>big difference. So ISA should more than well cover
the requirements

There are ISA and EISA 100bT cards around

Thats right, does the cable modem run on 100 base T ????? or 10 base T
So a 10base T card will more than do you, unless you want to throw away good
money??
So how can there be any drawbacks

The initial install (if you turn off the PnP on the card) deosn't need any
parameters passed at all with these cards !!!

Can't tell 'bout card specific issues, but I've compiled for my statistics
course a perfomance study with NFS between HP9000/HP-UX 10.20 machine, pair
of Linux-2.2 PC's and one Linux-2.0 server in 10BaseT network. Here's the
best rsize/wsize combinations I found:
Server Client wsize rsize
HP-UX Linux20 8192 8192
Linux22 4096 4096
Linux20 HP-UX 4096 8192
Linux22 4096 8192
Linux22 HP-UX 4096 4096
Linux20 8192 8192
Linux22 4096 8192
With Linux-2.2 server, knfsd were used. Speedwise the best combination were
Linux-2.x server with Linux-2.2 client.
The measurements were made with copying 20MB's of random data back and forth
between client machine and mounted share, measuring the total time of
operation. I've found out that especially with 2.2 kernels (tested 2.2.1 and
2.2.5) the blocksize has quite dramatic effect on NFS speed eg. with 1024
Linux-2.2 were slowest of 'em all and with 4096/8192 it were clearly the
fastest.
KNFSD were a bit disappointment because it had virtually nil effect on
performance compared to the userland nfsd - at least with these kernels.
Hope this helps.

Date: Mon, 31 May 1999 07:12:56 +0200
I finally got IP-masquerading work.
A tip for all SuSE users. You have to manually edit /etc/rc.config and set
ip_forward = yes!!!!!!! Otherwise it doesn't work.... I was searching for
hours to find that out :-(
But here's my question. I found out that if one PC in the network (we only
have to, but who cares) starts i.e. a download the whole bandwith of the
modem is fed up, so that the other PC(s) creep with some bytes/sec through
the internet.
Is there any possibility to limit the bandwith of every PC to a max.
amount???

James
