Re: Good boot and run on ancient laptop (HP Omnibook 5000), 16MB RAM
Martin Reindl, reading only what I actually posted, was moved to say ... your laptop does not seem to have audio(4) hardware anyway. Yeah. You see, a cosmic ray came and interfered with the posting of my dmesg, such that the SMTP server caught a . prematurely, and the TCP seqnums all magically fell into line with the truncation. The mere idea that I could have loused up the cut-n-paste of my dmesg to miss out the last 17 lines or so is unthinkable. Just to prove that the universe conspires against me, I'll repost the entire dmesg, and again the lines with the audio hardware and the 'root on wd0' will disappear. Never admit to a mistake, always allege a global conspiracy ;-) Looks like this laptop will do duty as little more than a serial terminal and rogue(6) platform, at least with the paltry 16MBs - having stuffed two 3C589 NICs into its two PCMCIA slots, brconfig is willing enough to create a bridge, but packet forwarding grinds to a halt after a few minutes only. I'll see if the backs of cupboards mightn't yield a little more RAM, which can't but help (and so might disabling devices whose interrupts I really don't want the poor little thing to waste its time handling, like the fdc0, joy0, and wss1 devicen.

Good boot and run on ancient laptop (HP Omnibook 5000), 16MB RAM
Unearthed an ancient laptop recently, intending to add it to the collection of 'near-transparent' logging bridges available. Keen-eyed dmesg readers will note the massive 16MB of RAM, and the absence of a floppy device (though the controller is found) - and a Pentium old enough to need the F00F workaround!! Not only no floppy, but no CD drive to hand either, and though unusually this laptop model has built-in SCSI, it won't boot off SCSI devices. Installed OpenBSD by taking the hard drive out, putting it in a USB-to-laptop-drive adaptor on another machine, booting off the OpenBSD install CD (which detected that adaptor and the disk attached to it just fine: how lovely!). First boot when reinstalled went just fine (though if I had a brain I'd have edited the /etc/fstab to change the mountpoint for / from /dev/sd6a to /dev/wd0a while it was still in the write-the-install machine - but a swift 'mount -u -w /dev/wd0a /' fixed it up fine for that boot). As the laptop is very slow processorwise, *much* patience was needed during the sshd 'generating DSA key' stage - took several *minutes*! I did have some memory of reading what turns out to be FAQ 4.12.3, and I was patient, but not smart enough to take the steps described there about doing the keygen on a respectable box and creating a site38.tgz! Though slow, the machine seems to work just fine in its intended role - it just captured packets to and from a new box running Kn*ppix (purely to compare hardware detection results, honest ;-) with two classic 3com 3C589 PCMCIA NICs in its two slots. And the dmesg below comes to you via a Jaz cartridge written on the laptop in question and read on this other box, so that 'works' too. No serious stress-testing yet, of course - but a large thumbs up to OpenBSD putting otherwise-ancient hardware to good network monitoring use! I'll be doing the 'config -e' dance to disable the unwanted audio hardware... later... and no, I don't intend running X on this!
