NetBSD/arm26 experimental snapshot, 2000-04-15. This directory contains a kernel and bootloader for NetBSD/arm26 as of 2000-04-15. They are by no means fully functional, but the system gets up as far as running user processes. To use it: gunzip netbsd.gz, since BBBB can't handle gzipped kernels. Put netbsd and BBBB on a filesystem accessible to RISC OS (preferably local). *SetType BBBB BASIC Reboot RISC OS, holding down keypad-* (and shift if you have Boot configured) to get a Supervisor prompt. This has to be a hard reset (ie power-on or ctrl-reset). Change to a 256-colour screen mode (eg *echo <22><15>). The rasops drivers are currently broken at any other depth, and don't support 16-colour modes at all. Run "*bbbb". The RAM disk (md0) contains an init which will fork and then run up and down the stack checking its registers aren't corrupted. Ctrl-Alt-Esc will get you DDB. Root on et (Ether1) devices works too, but only uses DHCP. Supported hardware: ARM2, ARM250, ARM3 CPU. 4Mb -- 8Mb RAM. Arc keyboard, mouse, RTC. On-board video, but no mode changing and only 8-bit mode. Acorn AKA25 (Ether1) podule. Maybe D.T. Software IDE. Bugger-all else. Oh, and dmesg is a small BBC BASIC program to pull out the kernel message buffer after a reboot (preferably before starting the desktop) and save it in dmesg/out. If you test this, please e-mail me and tell me how well it worked. Send dmesg.out if you can.
