What about Ultra-DMA?
HomeUltra-DMA, also knows as UDMA, Ultra ATA, or Fast ATA-2 , is a further enhancement of the EIDE disk-drive interface, available on the newer G3 Macs and on some PCs (Intel 440TX, LX, BX, and later chipsets; VIA/AMD VPX, VP2/97, AMD-640 chipsets; Promise Ultra33 (FastTrack) controller. Win95 and WinNT require an upgrade to exploit UDMA; Win98 supports it fully). UDMA drives tend to be a lot cheaper that SCSI-3 drives, and are often capable of stutter-free capture and playback of DV data.

edit] Q: Why is DMA disabled by default and how do I enable it?
Using FAQ - Knoppix Documentation WikiKnoppix does the very best it can to automatically figure out what hardware the PC has & it does this without human intervention. DMA is a feature that speeds up data tranfer on IDE devices such as CDROM drive& HD drives. Some chipsets and/or harddiscs are broken or buggy. Using DMA would cause problems on such systems. If your system works properly with DMA, and you are booting from HD, you can enable it by typing "/sbin/hdparm -c3 -d1 -m16 -k1 /dev/hda" or by editing the "/etc/init.
What is DMA and why should I have it enabled?
Showshifter Support - Frequently Asked QuestionsDMA (Direct Memory Access) is a system whereby the peripherals on your computer can transfer data to and from memory directly, without going via the CPU.

What is Ultra ATA/66?
FAQ-Frequently Asked Questions and Answers on ATA 66 ATA66-B...Ultra ATA/66, also known as Ultra DMA/66, enhances existing ATA (IDE) technology by increasing both performance and data integrity. This new high-speed interface doubles the Ultra ATA/33 burst data transfer rate to 66.6 Mbytes/sec. The result is maximum disc performance using the current PCI local bus environment.

How do I use DMA channels?
BitCtrl Systems -> QNX® Distribution -> FAQDMA channels are programmed using Port I/O calls, which are covered in section A). The memory DMA'd from and to should be "DMA SAFE". Before QNX® version 4.24 the shared memory routines always allocate contiguous memory. In 4.24 this changed. Now the only way to allocate DMA SAFE memory with the qnx_segment_alloc_flags() routine. There is a _PMF_DMA_SAFE flag as well as a _PMF_DMA_HIGH flag. Use the DMA HIGH flag if memory above 16Meg is ok, or in other words, you have a PCI adapter.
What are all of the DMA modes & what are they used for ?
GB DEV FAQsThis is the original DMA that is available on all models of GB. It is used to do a fast copy of sprite attribute data to Object (sprite) Attribute Memory (OAM) located at $fe00-$fe9f. Sprite attribute data includes sprite X & Y coordinates, tile number, palette number, horizontal flip, vertical flip, and sprite priority. No tile graphics are transferred using this method of DMA. Otherwise known as Horizontal Blank DMA. It is only available on the GBC.

How can I do a DMA Putpixel or DMA Mem-to-Mem copy?
PC Demos FAQ -- Official FAQ of comp.sys.ibm.pc.demosYou shouldn't bother. Not only is the DMA controller limited to 64K segments, but only on the slowest PC's (we're talking 8086 here) is it faster than doing a REP MOVSW. Still, DMA memory transfers take no CPU time at all, but you still shouldn't use them because they're just too slow on modern PC's. If you really want to do it anyway, just to see if it works, here's a small article from 1989 by Patrick & David O'Riva that can help you.
