I need to correct myself here.  I have fully updated my
machine with the latest stuff, but I cannot boot with
the latest "kernel-2.6.11-1.14_FC3".  The machine hangs
about midway into getting all the hardware up and going.

I have posted the details elsewhere and they can most
likely be found with Google.

I alternate between OpenBSD and Linux.  When I use linux
(FC3 actually) the latest kernel that boots is
"kernel-2.6.10-1.770_FC3".  This kernel thinks my
hard drive is "sda" (it is really PATA, not SATA) and
my CD/DVD drive is "hdc" and I cannot enable DMA to
the CD/DVD drive.

Unfortunately, the Dell BIOS doesn't provide a means to
disable the SATA hardware.  If it did, this problem
might go away.

Does your T43 use a PATA or SATA hard drive?

If PATA, can you disable the SATA interface in the BIOS?

I noticed a new FC3 kernel is about to come out, I hope
this problem has been fixed with it.

I looked for it on Google and found discission of patches
but none which seemed to address my specific issue.  You
didn't happen to save the message or the patch did you?

I would really like to use the CD/DVD drive, I can wait
for the S3 suspend/resume feature.

Thanks,
