Unhappy Insert scsi pcmcia card kills existing ethernet card


Hello all-
I'm pretty much a newbie still, and this seems like a HW issue, so I'm asking for help please.

Background:
I've got an old laptop (133MHz/32Mb) running Slackware (8.0 on kernal 2.2.19) in my home network as a DHCP server for the other clients in the house. That has worked fine for months.

After reading an article about Amanda (tape backup, www.amanda.org), I thought I'd try that on my system with hardware I already have around. (HP external 4mm DAT, and "New Media" SCSI card.

The laptop has a megahertz xjem3336 combo ethernet/modem pcmcia card.

Problem:
When I add the "New Media" "Bus Toaster" SCSI pcmcia card too and reboot, the ethernet card doesn't work, pings in or out fail.

Unplugging the SCSI card and rebooting makes the ethernet work fine again.

When I plug the scsi card in while 'hot', the card services seem to load the aha152x module fine, but the scsi 'vendor, model' information isn't displayed. (is there a command I'm supposed to type to do that part?, i.e. identify the devices connected to the card.)

I've attached dmesg/lsmod/ and proc/interrupts below for Just the ethernet card installed, and for Both installed. It looks like both cards use different irqs. I don't know what to try next.

Any help will be appreciated, Thanks.
