I was taking a look at an old Multia that's been sitting idle for a long time. It does not boot normally, but I'm able to do a fail-safe boot from the FSL image on floppy. When that boots, it spews a bunch of machine checks on the serial console. Before I write this system off, is anyone able to infer anything from these messages? If there is something I could do to fix it, I'd love to know. There's pretty much no FRUs on the VX40s other than RAM however, and I swapped in multiple pairs of SIMMs in one bank at a time to no avail. TIA.
