DMA and CDROM Drive

[Gerard Seibert]

I am running FreeBSD 5.3. I have it presently loaded on an older Compaq
5140 computer. For some unknown reason, I am having a problem getting
DMA turned on for my CDROM drive. I am also receiving an error message
regarding the 'slave'. I had FreeBSD 5.2.1 loaded previously and never
received any such warning message. In addition, the DMA was initiated at
bootup with the same entries I now have in the 'LOADER.CONF(5)' fiie. I
reformatted the HD prior to installing the new version, so I do not
believe that the problem lies there.

Here is my 'dmesg' output:

I am able to turn on DMA for the drive using the 'atacontrol(8)'. I have
not had success getting the DMA initiated using the /boot/loader.conf
file however. This is my 'loader.conf' file:

snd_ess_load="YES"
hw.ata.ata_dma=1
hw.ata.atapi_dma=1
hw.ata_wc=1

I have tried using parenthesis around the numbers as well, but the results are the
same.

I am open to any suggestions.

Thanks!

Only in America...

Tim Allen, comedian, had this to say about Martha Stewart:

"Boy, I feel safer now that she's behind bars. O. J. & Kobe are walking
around, but they take the one woman in America willing to cook, clean,
and work in the yard  and haul her ass to jail."
