Adam, I did a pretty extensive write up on the T23 I recently purchased. I imagine the T21 won't be too far off. Really need to get that write up on a web page someplace as an easier reference that I can actually update. Anyhow, rather than repost all of that, here are the relevant articles I wrote in the archives. Thinkpad T23 Setup (part 1) http://www.freebsd.org/cgi/getmsg.cgi?fetch=135463+147430+/usr/local/www/db/text/2002/freebsd-mobile/20020519.freebsd-mobile Thinkpad T23 Setup (part 2) http://www.freebsd.org/cgi/getmsg.cgi?fetch=147430+154009+/usr/local/www/db/text/2002/freebsd-mobile/20020519.freebsd-mobile Thinkpad T23 Setup (part 3) http://www.freebsd.org/cgi/getmsg.cgi?fetch=154009+159374+/usr/local/www/db/text/2002/freebsd-mobile/20020519.freebsd-mobile There is a more up to date patch that Orion did up a while back that apparently still hasn't been MFC'd for ac97.c. The patch described in the part 1 of my post does work, and it's a far simpler tweak. The good news here is that it looks like the 2 pr's that were referenced in my post have beem MFC'd, and should be available for you to use by doing a make world on a recent cvsup of STABLE. Have fun with it! These here Thinkpads are pretty nice boxes once ya get 'em all tweaked into play. adace@orbitz.com wrote: > Quick Hardware Summary: > > * IBM ThinkPad T21 > * Model: 2647-87U > * Audio Chipset: CS461x > > Relevant Kernel Config Options: > > options PNPBIOS > device pcm > device csa > > Resulting Kernel Messages: > May 16 11:54:25 ganymede /kernel: csa0: > <CS4280/CS4614/CS4622/CS4624/CS4630> mem > 0xe8000000-0xe80fffff,0xe8122000-0xe8122fff irq 11 at device 5.0 on pci0 > May 16 11:54:25 ganymede /kernel: csa: card is Thinkpad 600X/A20/T20 > May 16 11:54:25 ganymede /kernel: pcm0: <CS461x PCM Audio> on csa0 > May 16 11:54:25 ganymede /kernel: device_probe_and_attach: pcm0 attach > returned > 6 > > I found one email in the freebsd-mobile archives that indicates that this > simply doesn't work.
