I'd like to install NetBSD1.0 on a Western Systems 486DX2 (33/66MHz) system.
Systems specs are : AmiBios dated 01/12/1994, 8Mb Ram, 504Mb IDE drive,
Paradise video, 256k external cache on the processor (I think).
Symptoms: Booting from kernel floppy all goes well, then I get the 'insert
root filesystem floppy' prompt. On feeding tthe root f/s/ floppy I get the
2 copyright lines and then the system crashes before displaying the CPU
ident line.
Anyone have any ideas? Is there a problem with 486DX2s? or is it something
else ? Replies urgently requested. I *need* this system to do some real work.
There are *bunches* of 486DX2's running NetBSD (including my AMD
486DX2/80 :-). Your CPU shouldn't be the problem.
Try disabling features of your motherboard, like shadow ram and things
like that. If that doesn't help. try disabling motherboard and/or CPU
cache, and see if it runs any better. Some motherboards have very
brain-dead cache designs which don't work right under protected-mode
operating systems.
