Backport of ServerWorks ATA to 4-Stable?
Hello all. I was wondering if there would be a backport of the ServerWorks GC chipset (CSB6 South bridge) to 4-Stable. I am only able to obtain BIOSDMA support on my HD's and basic PIO support of my CD-RW. I played around with 5.0-Current on this machine and by utilizing 'atacontrol', I was able to get DMA mode transfers on all of the installed media. There were also no stability issues running in this mode either under 5-Current. Failing any plans by the developers to include this support into the upcoming 4.8-Release or later -Stable code, would it be possible to try and hack the -Current code into -Stable myself?

My understanding of the problem with the ServerWorks chipset was the inability to recognize slave drives; I still have this problem but have just put the server together so have not worked on it much yet.

There were also no stability issues running in this mode either under 5-Current What were your atacontrol settings, and how did you differentiate the results (dmesg, sysctl)? FWIW, my drive recognition problem exists in 5.0 and 4.7-Stable. I'll forward separately to you a message I received a couple of weeks ago on this or a related issue.

Hi, Kevin. I, too, have the Dell PowerEdge 600SC. Here is my IDE configuration: - 120GB Western Digital on primary master. - Plextor CD-RW on secondary master. - Lite-On DVD-Rom on secondary slave. I've been running the 4-Stable series of FBSD for quite some time now and just relegated the lack of support of the ServerWorks Southbridge to should be here soon. Just for grins, I installed 5.0 and cvsup'd -Current. While running 5.0, I was able to throw the primary HD into UDMA100 and noticed a fair amount of increased visual performance. The same went for the CD-RW and DVD-Rom, under UDMA33. I burned a number of full CD's and made a number of full dumps of various DVD's to the HD without issue. Also, with the CD-RW and DVD-Rom, while running under 4.x, there is quite a hit on the interrupt activity as reported by `top` while copying large amounts of data. On 5.0-Current, there was virtually none. This is about as scientific I've gotten with this thus far. :p In regard to your machine not being able to recognize slave devices, I don't really know. I've both the CD-RW and DVD-Rom on the secondary controller without a hitch, and one HD on the primary master. What were your atacontrol settings, and how did you differentiate the results (dmesg, sysctl)? If I remember correctly, I used the following under 5.0: atacontrol mode 0 UDMA100 UDMA100 atacontrol mode 1 UDMA33 UDMA33 Attempting to place the secondary controller into DMA mode under 4.x, the machine would lock up shortly after. One other thing, the dmesg for 4.x states the following: pcib0: ServerWorks host to PCI bridge(unknown chipset) on motherboard Where as under 5.0, the dmesg correctly picked up and displayed actual support for the CSB6 Southbridge. I don't have a dmesg handy for this. - John __ Do you Yahoo!? Yahoo!
