DMA question
My BIOS says it's configured for PNP OS. I'm running XP/SP1.
When I boot, the BIOS shows my two hard drives as DMA5/PIO4 on pri and sec IDE controllers. When XP boots up, I go to Device Manager and look at the IDE controllers. The resource tab doesn't show DMA enabled (no DMA channel specified). The "Use automatic settings checkbox" is grayed out. Two questions: 1. Is DMA really enabled but XP just doesn't indicate it? 2. If DMA is not enabled, how do I go about unchecking the "Use auto settings" box and manually enable it? Thanks. Dave |

Dave Dave, don't know if this is actually causing your problem, but you need to disable the pnp os option in your bios. That was for older operating systems, by disabling it you let Windows XP completely control assigning resources, etc. Don Burnette |

Not so. PNP needs to be on for Windows to detect and assign resources.

DMA question
Absolutely not, not in the bios.
If pnp os is on in the bios, then the bios is going to fight with the OS for resources, it should be off to allow XP to assign everything. It was true in the earlier days, ie win95, but not today. I have installed and run both XP Home and XP Pro with this setting off in the bios, since Dec of 01, and have no problems whatsoever. Don Burnette Unknown wrote: Not so.
