Another, of course, is how the time spent trying to bring it up and the education gained thereby would compare with just requisitioning a card for the borked motherboard. Yet another question could be how much the lab wants to invest on a slow motherboard with broken curcuitry (which might also depend on what borked the on-board ATA controller). ATA controllers can be pretty cheap, particularly if you don't need to boot from them or build raid on them. Motherboards aren't necessarily all that expensive, either, especially if the application doesn't demand fast response. > # kldload snd_sb16 > # kldstat > Id Refs Address Size Name > 1 9 0xc0400000 275764 kernel > 2 2 0xc0676000 18a44 miibus.ko > 3 1 0xc068f000 6b98 if_rl.ko > 4 1 0xc0696000 b1b8 random.ko > 5 1 0xc1118000 4000 snd_sb16.ko > 6 2 0xc111c000 18000 sound.ko > 7 1 0xc113b000 4000 snd_sbc.ko > > # cat /dev/sndstat > FreeBSD Audio Driver (newpcm) > Installed devices: > pcm0: <SB16 DSP 4.13> at io 0x220 irq 5 drq 1:5 > bufsz 4096d kld snd_sb16 (1p/1r/0v channels > duplex default) > > Anyway, if I buy a PCI IDE controller, would that > work easily with FreeBSD (4- or 5-Stable alike) ? If you do buy a controller, check the hardware compatibility list and also check that the board works with a slow, older motherboard. My impression is that support for some boards is not compiled in, so you may be faced with compiling your own kernel. (If I understand the handbook correctly.) I am faced with exactly this question, but I have a lot of other problems with higher priority, so I've been dodging it. -- Joel Rees <rees@ddcom.co.jp> digitcom, inc. $B3t<02q<R%G%8%3%`(B Kobe, Japan +81-78-672-8800 ** <http://www.ddcom.co.jp>; **
