Re: 7.1 on a IBM 43P, 7248-132

Finally have a working firmware for the SCSI2SD device (replaces the 
SCSI2 HDD). This firmware works with the 7248-132, but in general 
probably supports anything using a Symbios Logic 53c810 (fast scsi) 
controller.

If you've been able to load NetBSD on your machine, have you had any 
trouble with the integrated ethernet freezing the machine when trying to 
bring up the interface?
"ifconfig pcn0 up" will cause my machine to lock up.
