Hi,
I built a custom kernel to enable my 2nd CPU, and now when it boots, I get error messages and it hangs at a dump....I'd like to get in a move my origional kernel back, so that I wont lose everything i've done so far.  However, the NetBSD instructions say to "hit the spacebar during the 5-second timeout" when you boot up, I assume at some boot manager screen?...well, i dont have that option when i boot. it goes directly into booting up NetBSD.  Any ideas? i can boot from the cd and get a command line, but i'm a little lost as to what to do next.

Thanks,
Reggie

ps. doubt this will help but its a sparcstation 20, dual ross 125's, 2 scsi disks, cdrom, fdd...
