11214	2001-04-12 00:29:00	I have bought a new hard drive and would like to set it to DMA mode (pretty sure it supports DMA mode, since Seagate says so). Now I have set it to DMA in Windows 98 SE (Control Panel, System, Devices.. Hard Disk Controllers.. so on) But my question is How can I be sure that it's set in the BIOS (I am using Award v6.00PGN, which comes with the BCM VIA BC133KT-100 motherboard). Also I have 2 hard discs (physical IDE drives), one which supports ATA-100 and the older one supports ATA-66, the computer sometimes crashes if I try to set the older one to DMA, (But the new one is OK). So again, it comes down to how to recognize whether DMA is set in the BIOS. Just an additional question, could someone please enlighten me as to the difference between DMA, ATA-100 and ATA-66? Any help is appreciated. Thanks in advance - James Jiao	Guest (0)

DMA stands for Direct Memory Access, and DMA bus mastering was the technology prior to UDMA, ie. Ultra DMA. The burst data speed transfer rates are 33MB/sec for udma/33, about twice as fast as the previous technology, and so on for /66, /100. Go into your BIOS at boot up by pressing the appropriate key(s) for your computer, you will probably find a page called Integrated Peripherals. If there are entries like 'IDE Primary Master UDMA', set the options to auto for each of them. Ie. let the BIOS set the controllers for your hard drive types.	Guest (0)
