Sun E250, NVRAM edit? (Serial Speeds, no console, etc)

Progress last night. Pulled the NVRAM (STM M48Y59 or something) and threw it in the Needham EMP-100. Read contents, nothing that looked like any sort of config really. I noticed on the mainboard there is an Intel TSOP Flash IC so that might store a bunch. Saved the contents, wrote all FF's. Checked to see if it retained that (is the battery dead?) It seemed to for 1 minute. Shoved it in the E250, and got both graphics console and serial output finally. It again complained that the NVRAM contents were invalid (same as with the NVRAM IC removed) but this time I could actually type on the keyboard. Got past it. Did a factory defaults option on the NVRAM. Then boot kicked it into Solaris. I will hopefully find a Solaris 5.10 sparc ISO on archive.org and the last step is to reset root password. Ethernet won't work until I re-program a MAC address into the NVRAM, but those instructions exist out there. I also found on the mainboard there was a set of jumpers labelled RS-232 / RS-483? 482? Some other odd standard that isn't 485 and 422. It looks like the were set to the strange one, so I moved them over to 232. -- : Ethan O'Toole
