DMA mode

[VeryTired]

hi, i have just recently formatted my computer, and when i check the device manger it for my primary IDE channel (having a hardrive as the master). They have detected my LG cd-rom CRD-8522B to use DMA trasnfer mode...But after like 1 month now....i have no idea what happen...it changed back to PIO mode I checked their site for an update or something but there was nothing. Now i wanna know what can i do to get back the DMA mode cause it does not make sense...

Specs.
p4 1.8
512 ddr ram
80gb
Win Xp Pro

Under the advanced tab on the IDE properties, isn;t there a drop down box where you can change it?

You might want to update your AGP drivers also.

why would i want to update my agp drivers....what does my vid card have to do with it?...and yes theres is a drop down box...option is "DMA if available" and i set it that....then it still runs it as PIO..

[Droppyale]

agp is not video card drivers... it's the motherboard drivers.....

what motherboard do you have? check the manufacturer's website for drivers.

How do you have the CD configured in the machine ie: Is it on the primary or secondary IDE channel and do you have it as Master or Slave?

[Droppyale]

I have my CD-rom as master on Primary IDE 0.

and my Hard Drive as slave on Primary IDE 1.

[Droppyale]

My CD-Rom is on DMA 2 mode

and HD is on DMA 6 mode

I was asking VeryTired how his devices were configured but since you posted this info I think most, probably including the device mfg's, would say that you have the two reversed and almost guaranteed most HD mfg's will tell you to never have an optical device on the same IDE channel as your HD.

[Droppyale]

yeah I know that... but I have 2 other IDE devices so I have no choice...


it's not really abig deal..
It works great, and the HD doesnt loose any performance....

i have my hd on IDE 0 which is master, and my cd-rom IDE 1 which is slave. It allows my harddrive have a DMA status, but my cd-rom's DMA is disabled and no matter what i do in BIOS, it won't change it. I have a Asus p4 s533 motherboard.
