My workbench area that will live under one side of the layout is coming along nicely. Here are some shots of the open grid benchwork along the far wall.

Finishing up the first wall.

The old workbench moved into position. The plan is to extend the workbench for the entire width of the wall. Can a workbench ever be too big?

Tuesday, August 29th, 2006Install Debian on Sun Netra T1 105
Monday, August 21st, 2006I recently acquired a Sun Netra T1 105 to play with. A few eBay purchases later and I had 512MB of RAM and a couple of 9GB Compaq SCA drives installed. Debian is pretty well supported for sparcs so that’s what I chose to install. The install was done over serial console as this box doesn’t have keyboard or framebuffer support.
After netbooting a kernel image following the instructions here the rest of the install was just a normal Debian install.
After the install and rebooting the machine I was greeted with a trap 3e error and an ok prompt. From googling it looks like this is a common problem with several possible causes. The fix that worked for me was to put a small script in nvram (I LOVE real server-class hardware).
ok setenv use-nvramrc?=true
ok nvedit
0: probe-all install-console banner
1: probe-scsi install-console banner
2: ” Working around Trap 3e” type cr
3: boot^c
ok nvstore
ok reset-all
ok nvedit
0: probe-all install-console banner
1: probe-scsi install-console banner
2: ” Working around Trap 3e” type cr
3: boot^c
ok nvstore
ok reset-all
Note: line 3 is “boot” followed by a Ctrl-c to get back to the ok prompt
For some reason on this machine I had to do a probe-all followed by a probe-scsi for it to pick up the SCSI drives reliably after poweron.
The combination of a LOM (Lights Out Management) module and OBP (Open Firmware Prom) make for easy server management.
This website is now hosted on this machine in my basement.
