Yep, first error in part 1 was with the device in PCI slot #4, which is the JVS I/O board. I removed that and turned it on again in part 2, and it got a bit further, but the resolution was set incorrectly for whatever game is stored on the hard drive. Since then I changed the dipswitches to display 640x480, but the next error was about the missing I/O board.

I'm hoping that if I replace the CR2032 battery in the I/O board, it might work again, otherwise I can pull another one out of my Lindbergh Blue.
Got a lot further than the blank screen I was getting before. =P All it took was a replacement CPU.
It all started because my secondary desktop PC gave up the ghost - either a faulty mobo or psu, couldn't be bothered investing any further in it as it was a shitkicker freebie. A week or two later, I was fortunate enough to stumble across an abandoned P4 PC in my unit blocks with the old school 478 socket, same as Lindbergh. I pulled out the cpu and heatsink/fan out of my Lindbergh Yellow (the two are fused together) and tested it in my PC, and it wouldn't boot. So narrowing it down to a problem with the CPU, I bought a spare for $10 and a new fan/heatsink. Problem solved.
Also confirms that Lindbergh runs on Intel Pentium 4 3.0Ghz HT (800Mhz FSB - 1MB L2 Cache). Couldn't confirm from stamp on top due to the heatsink, but they looked identical from underneath (stamped with a "003"), and it boots, though I don't know whether it would still boot with a slightly different spec P4.
