Id be gratefull if some1 could give me some advice with regard to optimum configuration of drives for the following setup.
For some reason I have recently encountered a significant drop in performance, I can only assume this is to do with my installation of the actuall drivers for my MB rather than letting windows sort it out, could any1 explain why this should be the case?
Unfortunately theres nothing techincal about my observations about performance lol. I play a lot of computer games, in particular quake 3. With the installation of the MB drivers i noticed a significant increase in loading times (rather drastic change tbh).
Im considering removing these drivers and returning to the MS ones and attempting some kind of bench mark test using that sandra program. Would this be a worth while venture?
The via drivers are required to allow my gfx card to run in AGP mode but presumably i could remove just the part releting to the ide controller?
With regard to DMA, it is enabled for both HDs on the one ide channel however if i attempt to enable it for the optical drives I completely "loose" my secondary IDE channel (thus the optical drives being unrecognised) forcing me to remove the controller and resinstall it. Ive no idea why this is but all drives are consistanly detected by the bios on start-up, its just windowz having a fit :S
Just fathomed that i only have 40 wire cables, this obviously stifles performance but its always been like that so i still cant understand the change
Using 40 wires cables instead of 80 wire cables does not in itself reduce performance. 80-wire cables were invented to reduce signal crosstalk at high transfer speeds. If you use a 40-wire cable and UDMA is enabled you should get the same performance but with a potential risk of datacorruptions.
Note: Its possible for the mainboard to detect which cable is used, and force a lower transfer speed. I dont know which (if any) motherboard actually do this. So check that UDMA is enabled for the drive. For now ignore the cable, but in the long run you might want to change it to an 80-wire so you are sure datacorruptions doesnt occur.
Whoa... that rates pretty high on the "wierd-o-meter"
enabling DMA disables it for the 2nd-ary HDD. damn strange.
Some sort of benchmark would be helpful.
But i suspect half of your problem is due to the elderly devices you are running.
As for the 40wire cables, that should be no problem with all your old devices, however it somewhat hampers you 60GXP, as it can transfer data at up to 40-50Mb/sec but the cable limits it to 30-33mb/sec.

I have DMA enabled for both hard disks on IDE0. However, when I attempt to enable it for the optical drives, both on IDE1 rather than Windows just switching it off as its not supported it "removes" my IDE1 channel, not detecting either of the CD drives on it :S Consequently I have to reinstall the IDE interface drivers. This is possibly caused by the CD drives not supporting DMA i dont know, but its a rather wierd resposnse, id have expected DMA just to be disabled again on reboot.
