That computer I mentioned recently, I added a SCSI card to it and enabled the second NIC. It’s now looking pretty sweet with 5.4 running on it. With the new additions, the dmesg now also contains:
port 0xd800-0xd8ff mem 0xff6fe000-0xff6fefff irq 17 at device 8.0 on pci2
I plan to make this box into a Bacula testing platform for FreeBSD 6.*, add a backup DNS server for my LAN, and make it my wireless gateway box. It’ll also have an external DLT added to it, just in case the Bacula project needs it.
Here is the service manual for that computer: http://support.dell.com/support/edocs/systems/opgx260/en/sm/.
