need help getting a Sun Ultra-10 working

Hello Folks, I just assembled an Ultra-10 (replaced memory, CPU, NVRAM chip, IDE hard disk, IDE CDROM) and it seems to be hanging somewhere. I don't get anything from the VGA connection on the 1280x1024 LCD monitor that is connected, but on the serial console I see the output pasted below. The system does not respond to any input via the attached sun keyboard/mouse or via ttyA after printing the last line in the output below. Obviously, the NVRAM battery is dead, and I'm working on getting a replacement. Does anyone have a good source in Germany? The chip says "M48T59Y-70PC1U". Could the dead NVRAM battery explain the behavior described? thanks, Rob Urban ----- serial console output BEGIN ----- Hardware Power ON @(#) Sun Ultra 5/10 UPA/PCI 3.31 Version 0 created 2001/07/25 20:36 Probing keyboard Done %o0 = 0000.0000.0055.4001 Executing Power On SelfTest @(#) Sun Ultra 5/10 (Darwin) POST 3.1.0 (Build No. 626) 13:56 on 06/27/00 CPU: UltraSPARC-LC (Clock Frequency: 300MHz, Ecache Size: 512KB) Init POST BSS Init System BSS NVRAM NVRAM Battery Detect Test *********************** STATUS =FAILED TEST =NVRAM Battery Detect SUSPECT=NVRAM U13 MESSAGE=NVRAM Low Battery addr 000001ff.f1001ff0 exp 00 obs 10 Status of this POST run: FAIL manfacturing mode=CHAMBER Time Stamp [hour:min:sec] 28:6a:c1 [month/date year] 0b/2c 2130 Power On Selftest Completed Software Power ON0.0000.0000.0001 ffff.ffff.f00b.31a8 0000.3333.0200.001b @(#) Sun Ultra 5/10 UPA/PCI 3.31 Version 0 created 2001/07/25 20:36 Clearing E$ Tags Done Clearing I/D TLBs Done Probing Memory Done MEM BASE = 0000.0000.2000.0000 MEM SIZE = 0000.0000.1000.0000 11-Column Mode Enabled MMUs ON Copy Done PC = 0000.01ff.f000.201c PC = 0000.0000.0000.2060 Decompressing into Memory Done Size = 0000.0000.0006.eba0 ttya initialized Starting real time clock...
