If you have a Thinkpad 600E and are trying to install v4.1 or later, the following will be of use to you: Run the PS2 utility and set the PCI IRQ to 9 so it will share with the smb/intpm stuff. Run the pccard stuff in polled mode. These two items will give you back two IRQ's. Apply this patch from Jonathan Chen to get pcm probing to work reliably: Index: sys/conf/files =================================================================== RCS file: /export/ncvs/src/sys/conf/files,v retrieving revision 1.340.2.38 diff -u -r1.340.2.38 files --- sys/conf/files 2000/10/31 23:16:07 1.340.2.38 +++ sys/conf/files 2000/11/30 05:10:55 @@ -1090,8 +1090,7 @@ dev/sound/isa/sbc.c optional sbc isa #dev/sound/pci/aureal.c optional pcm pci dev/sound/pci/csa.c optional csa pci -dev/sound/pci/csa.c optional pcm pci -dev/sound/pci/csapcm.c optional pcm pci +dev/sound/pci/csapcm.c optional csa pcm pci dev/sound/pci/ds1.c optional pcm pci dev/sound/pci/emu10k1.c optional pcm pci dev/sound/pci/es137x.c optional pcm pci In your kernel config file *do not* use PNPBIOS. If you do so, you will give back the two interrupts you got back above. The wretched DSP modem normally requires two (count 'em, two) interrupts to operate - one for the modem and one for the DSP chip itself. Using PNPBIOS makes the kernel find this useless hardware and allocate resources for it. The modem can be reconfigured to use only one interrupt, but it is still not useable under FreeBSD, so don't bother. The only hitch you will see in not using PNPBIOS is that the line for the sound card will require a fully-specified config line. Mine looks like: device pcm0 at isa? port 0x52c irq 5 drq 1 flags 0x10 If you don't use the patch above, you will see some kernel noise that the csa0 device probe_and_attach routine "returned 6" and the kernel will "trap 12" when trying to use *any* usb device. With the patch, sound and usb both work normally. With the two earlier adjustments, there are enough interrupts to run everything, including two pccards.

Modules vpo, if_tun, usb, ums, umass, and ugen are loaded by lines added to the /boot/loader.conf file. This kernel is capable of running a parallel zip drive, a SCSI cd or tape drive with an Adaptec SlimSCSI 1460-D card, and USB devices including a mouse, Y-E data floppy, and USB Zip drive. -- ________________________________________________________________________ Technology is dominated by those who manage what they do not understand. http://www.netcom.com/~scrantr/index.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
