I moved my HD & Ram from an intel M/B (no AGP) to a SIS M/B (w/AGP = ATI 9600 Pro). Repaired XP and added an new 160 Gb Maxtor - so now I have a 40Gb master and 160 Gb slave (all NTFS). Most everything is working, but not as fast as I'd like - I'm trying to build a DVR and too many frames are dropping (like 15-20%) when I record. I want to DMA enable the drives - ATI says this will help, but when I look at the setup in the BIOS it's PIO4, and when I set the DMA on the device it's set to Preferred DMA. Anyway, there is yellow indicator in the device manager beside the SIS Master Bus Controller. XP says it can't find the drivers. I've searched on "SIS Master bus Controller" on the internet, but nothing comes close. www.SIS.com is useless, unless I'm missing something. I've downloaded the SIS IDE Drivers, but not sure what Master Bus Controller is exactly looking for. Can I drop the device and have it autoload, or will I be doomed? Help!

Would help to know which SiS chipset you have and who made the board!
Its not a SiS board, they dont make boards!
Whats the bios string?

Swapping a harddrive with a boot-able OS to a new motherboard is "NEVER" a good idea.
You should search for posts relating to people Repairing XP and have problems on the "same" motherboard.

Fresh install on all NEW MBs

It is a P4S5A2 M/B [how can you tell who makes it - it's not even on the user manual???] with a (SIS, I guess) chipset 645/961. Intel P4 1.7 Ghz. I dropped the SIS Master Bus Controller and it never came back. It might have been a mistaken SIS IDE driver I installed (for the wrong chipset).

So the story goes okay now. Everything is pretty stable, except the cpu fan will not turn off in Standby. The computer is off our living room and it's pretty noisy. Shutting down is a pain - 'cause it takes a whole minute to boot up and add wireless connections, USB devices, etc. Return from standby is 10 seconds. I have applied every USB fix I can find and dropped and added USB devices, hub and contollers. I did add a PCI USB 2.0 card, but don't think it's the culprit. The bios doesn't seem to allow a setting change of S3 (STR) to S1 (POS) - I might have that backwards, my notes are at home.
Q1) How can you tell what is suspending the fan from powering down?
Q2) Could it be my ATI card?

This is a ECS mother board! P4S series!

Since you have a manual, did you buy this board new or second hand?
Where is the drivers disk for the board?

After looking at the manual, it seems to have the SiS XP4
(SiS645 DDR333 Chipset for Intel PentiumŪ 4 SiS961 MuTIOLŪ Media I/O)
This is the IDE driver site for this chipset:
