neat trick for any SparcStation running OpenBSD.
In /etc/sysctl.conf set machdep.led_blink=1 and reboot the machine.
This makes the power LED blink (it actually reflects the load average: the slower the blinking the higher the load, the higher the blinking the lower the load!). Sort of the reverse of what you'd expect, but still a handy indicator!
This has been tested on IPX's, SS2's, SS4's, SS5's, and I believe SS10's/SS20's as well -- so it likely works everywhere.... Try it out!
Sweet man. Nice little trick.
seems to work on a ultra 10....
