Keep just tried that other prog, notice TRIED. it went to start pc-dos then poof internal error 0222...........whats that...is my computer fixable, *** is wrong w/ this toad

also just tried enabling DMA and putting windows disk in hoping it would load and just let me start over.

PLZ someone figure this out it's so annoying

Setting this BIOS feature to Disabled forces the BIOS to disable DMA transfers for the IDE drive.

Setting this BIOS feature to 0 forces the BIOS to use DMA Mode 0 for DMA transfers.

Setting this BIOS feature to 1 forces the BIOS to use DMA Mode 1 for DMA transfers.

Setting this BIOS feature to 2 forces the BIOS to use DMA Mode 2 for DMA transfers.

Setting this BIOS feature to 3 forces the BIOS to use UltraDMA 33 for DMA transfers.

Setting this BIOS feature to 4 forces the BIOS to use UltraDMA 66 for DMA transfers.

Setting this BIOS feature to 5 forces the BIOS to use UltraDMA 100 for DMA transfers.

Setting this BIOS feature to 6 forces the BIOS to use UltraDMA 133 for DMA transfers.

Setting this BIOS feature to Auto lets the BIOS auto-detect the IDE drive's maximum supported DMA mode at boot-up.

Normally, you should leave it as Auto and let the BIOS auto-detect the drive's DMA support. If the drive supports DMA transfers, the proper DMA transfer mode will be enabled for that drive, allowing it to burst data at anywhere from 33MB/s to 133MB/s (depending on the transfer mode supported).

You should only disable it for troubleshooting purposes. For example, certain IDE devices may not run properly using DMA transfers when the PCI bus is overclocked. Disabling DMA support will force the drive to use the slower PIO transfer mode. This may allow the drive to work properly with the higher PCI bus speed.

Fount that on another site..one ? why don't i have the choice of modes? and my pci bus speed wouldn't be high w/ factory defaults would it? someone plz help
