I have a problem, a VERY frustrating one: First the hardware: 3/60 with 12M memory and NO keyboard or monitor, it's set up to use ttya as the console. One SCSI disk as sd0. Now the software: SunOS 4.0.3. Under SunOS 3.5 the system boots just fine with a terminal on ttya. Under 4.0.3; BOOOM! The startup sequence claims it can't find a keyboard and panics BIG TIME. When I add a monitor and keyboard and do a eeprom console=b&w from 3.5, 4.0.3 will boot and run just fine. I have 3 kernels I've tried and all fail if eeprom console=ttya is in effect. The generic 4.0.3 kernel dies just after the zs0 is printed out and 2/3 of a screen of :'s are printed out followed by a hardware reset and then the sequence repeats. A kernel configured with no monitor or keyboard also panics in the same spot with the same results. What gives with 4.0.3 that it can't boot on a 3/60 without a monitor and keyboard? As I said, 3.5 runs just fine under the exact same hardware/eeprom setup that causes 4.0.3 to blow up. I compared the 3.5 config file and the 4.0.3 config file and they're the same with additions in the 4.0.3 file for streams and other baggage. Where do I look in TFM to find a solution to my problem? I've poured over eeprom, startup and all the man pages I could find on kernel config but nothing explains what's going on here. I know the next part of the startup sequence after the zs0 line is zs1, the keyboard and mouse. I assume 4.0.3 doesn't like the fact that I have a 3/60 but no direct keyboard/mouse hooked up to it. WHY? Any help or hints would be GREATLY appreciated, -Rob Healey rhealey@ub.d.umn.edu rob@com2serv.c2s.mn.org
