The net 4801 arrived well wrapped and boxed but it was soon lidless. I noticed a 32M flashcard fitted and read about the OpenBSD-3.4 OS installed thereon. A nice touch to have a minimal working BSD of some kind pre-installed. The card is to be returned to Wim when finished with. The first power supply I tried (after checking correct polarity/ voltage etc.) failed because the inner sleeve was too wide for the pin in the socket. Made a better null serial lead, connected the soekris to a 4.9 box on the LAN, ran 'cu -l /dev/cuaa0 -s 19200' as root and powered on. comBIOS ver. 1.24 20040312 Copyright (C) 2000-2004 Soekris Engineering. net4801 0128 Mbyte Memory CPU Geode 266 Mhz Pri Mas TOSHIBA THNCF032MBA LBA 496-4-32 31 Mbyte PXE-M00: BootManage UNDI, PXE-2.0 (build 082) etc. Pressed ^p within the 5 second countdown for the BIOS prompt and had a look at some settings. Quickly forgetting where I was, I tried up arrow for history and lost keyboard input (or echo). "~." or reboot got it going again. Watched OpenBSD boot on the serial console until cu disconnected as the OS took over the port. But cu again connected to a ksh shell in the <32M install. It's cheating but I took the easier way and put the laptop drive in the desktop, with one of those handy adaptor leads, for faster kernel builds. Installed 5.2.1 minimal and sys (kernel sources). After a few mistakes (one error was 'unknown option "SHED_4BSD"':)) and the addition of the two options described at: http://phk.freebsd.dk/soekris/kern48xx.html the kernel built and installed. It was odd leaving out vga, fdc and vt devices. I was surprised to find no sign of the drive when fitted to the soekris. 'set FLASH=3DSecondary' soon fixed that. If I'd remembered to change the ifconfig line to sis0 it would have worked first time. Setting the ttyd0 line in /etc/ttys to 'on' would have helped too. The kernel is about 3Mbyte smaller than generic: chucky# ll /boot/kernel.old/kernel -r-xr-xr-x 1 root wheel 5940286 Feb 23 20:45 /boot/kernel.old/kernel chucky# ll /boot/kernel/kernel -r-xr-xr-x 1 root wheel 2734753 Apr 19 19:42 /boot/kernel/kernel The HD mounting bracket only leaves room for the lowest profile drives. Anything fatter than 10mm and the case top cannot be fitted. The board is < 5.5" wide and a 2.5" HD is < 3" wide. Room for two of each side by side in a 19" 1U case. John.
