Hi,

for those reading my other posts about the 3Com 3c579 in an EISA
machine, since it didn't work, I tried to boot NetBSD on my other EISA
machine (486/50).

This machine has an Adaptec 2740 EISA SCSI controller and a 3com 3c509
ISA network card configured as an EISA device (thru a DOS utility).

The good news is, the Adaptec seems to be working fine. But the bad
news is, the network card does not work. :-(

The card is not configured. It is a TP-only version which seems not to
be recognized by NetBSD. I get a message like

unknown 3Com device TCM5095 at eisa0 slot 3 not configured

Hmm, I thought, maybe this version of the card isn't known to the
kernel, so simply tell him. I looked at the L+++x sources and came up
with the following patch:

(see at the end of the mail)

This patch lets the kernel recognize the card, but the card still
seems to be different to "regular" 3c509 cards, I get the following at
boot time:
(typed in manually)

---------
ep0 at eisa0 slot 3: 3Com 3C509-TP Ethernet
ep0: interrupting at irq 10

ep0: erase pencil mark!

ep0: erase pencil mark!

ep0: erase pencil mark!
ep0: wrote 0x7ff to TX_AVAIL_THRESH, read back 0xffff. Interface disabled
---------

Later the kernel panicks.

This is obviously not my day :-(

regards,
chris
