passes the friggin' TechTools tests, but won't install any OS I've tried. I've reset PRAM, removed all PCIe cards, tried every RAM combination possible with the sticks I have. but I can't get it booted enough to tell! The LOM should hopefully give me some more insight as to hardware issues. once configured, my plan has been to install ESX and run multiple VM's off the machine. I'm attempting to install 10.5 or 10.6 server *JUST* so that I can configure the Lights-out Management.
#Techtool protogo serial mac os
Installing Mac OS 10.6.3 server (other set of CD's I scrounged up) - installs, but then after reboot, hangs on the "Welcome" screen, and never progresses any further. Installing Mac OS 10.6.0 server, won't boot from CD. Running TechTool/ProtoGo repeatedly on it reveals no issues whatsoever. It would boot, get to the setup screens, and then simply beach-ball. Installed the OS, but then it hung repeatedly at boot from then on (left it 48+ hours, no response). I've not found anything on Google that identifies it, so I wiped the internal drives, and attempted to re-install OS 10.6 server on it, in order to configure the lights-out-management console and check logs. Appears to be 3-4 rapid flashes, then off.

Initial symptom was/is the amber "attention" light flashing, as soon as the system is powered up (before booting). It is a fairly recent acquisition, but worked perfectly for several weeks prior to the most recent issues. I have a 2009 (3,1 version) xServe that suddenly began exhibiting signs of hardware issues.

officially throwing in the towel on this, and asking for help.
