[comp.dcom.lans] Novell 2.15 & 3C523 Problems

grant@clleth.UUCP (Grant Fengstad) (10/20/89)

I've been experiencing some problems with Word Perfect running on
several IBM PS/2 Model 55's using Novell Netware 2.15 and 3Com
EtherNet Microchannel cards.

The system works fine on other applications it appears, but in WP
occasionally a workstation will hang and give the following error:

	3C523:SCB Command not cleared

The machine must be re-boot to continue on.  This happens whilst trying
to select the print menu mainly it appears.  I've analyzed the network
and it appears to be ok.  Does anyone have any ideas?

I have been doing a LAN driver for the 3c523, and experinced this
behaviour of the card during beta testing. The driver of the 3c523
must be able to detect a hung card (because it DOES happen, more often
on faster machines, 55 being a 386SX, right?). Your driver seems to be
able to detect it, but it must be able to reset the card to stay on
the air. Rebooting your machine off course resets the card.

A similar bug report for sunos was posted a couple of weeks ago, the
people there had source to fix the unix driver (the bug is in the
chips, which are also used in some VME ethernet cards). It sounds like
you have an old and/or dumb driver. When I did my driver, I had an
example driver from novell for the 523 to look in.  It did the right
thing. Try to get another driver.

If you already have a new driver, the board may be flakey, causing the
driver to be unable to reset the board after a hung. Then you should
have the card replaced by your dealer.

Hope this helps.
