I got it to load the kernel via tftp. Then it starts with: bootstrap code read in base = 1f2000, image_start = 0, image_bytes = 5f1027 initializing HWRPB at 2000 initializing page table at 1e4000 initializing machine state setting the affinity to the primary CPU jumping to bootstrap code halted CPU 0 halt code = 2 kernel stack not valid halt PC = 4 boot failure This is with the kernel from the 4.0-19990413-CURRENT snapshot at ftp.cdrom.com. I gunzipped the kernel (after extracting it from the boot.flp image with vnconfig), and got this file: -rw-r--r-- 1 sthaug wheel 6230055 May 15 17:23 /tftpboot/kernel The size is at least consistent with image_bytes = 5f1027. Any ideas? TIA! Steinar Haug, Nethelp consulting, sthaug@nethelp.no To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
