  Lexar — Compact Flash Memory Cards — Professional UDMA 300x
The Lexar Professional UDMA 300x memory card dramatically increases card-to-computer transfer rates when paired with a UDMA-enabled reader, as well as provides support for the next generation of high-resolution UDMA-enabled digital SLR (DSLR) cameras.
Lexar Professional UDMA CF cards are available in 2GB, 4GB, and 8GB capacities, and work with all CF devices.
The advanced technology and blazing speed of the Professional UDMA 300x CF card drastically improves download time, and also leverages the power of the next generation of UDMA-enabled DSLR cameras.

  Ultra-DMA HOWTO/Onboard UDMA interfaces - Leuksman
Some UDMA support is in the latest 2.0.x kernels I believe, and is built into current 2.2.x kernels for the Intel chipsets.
There is another patch that supports full UDMA mode at http://www.pyreneesweb.com/Udma/udma.html, designed for the VIA VT82C586B, and it ought to work on the VP2, VP3, VPX, P6 and AGP Apollo chipsets.
Follow the directions for installation and UDMA enabling there, but it is recommended that you back up any data you want to keep, as there are potential problems with incompatible motherboards.

 Ultra DMA drives problems with Windows 95/98, NT
But there seems to be a discernable minority of UDMA drives that have been installed in systems that aren't quite capable of supporting the maximum speeds that UDMA can produce.
One of the frustrating things about UDMA difficulties is that they may be intermittent and hard to diagnose.
If a drive controller has been configured for UDMA support with these drives in Windows 95 and NT and then Windows 98 is installed, the Windows 98 installation crashes.

 Controlling UDMA in Windows 2000
UDMA employs a new type of data transfer system, in that the disk controller has direct access to system memory for the purposes of moving data, without complete reliance upon the CPU.
UDMA is not enabled by default when installing Windows 2000, it must be enabled.
In order to enable UDMA and optimize it in Windows 2000, you need to do a little research, and the best place to start that research is with the components that make up your system.

 [No title]
UDMAJR ("Junior UDMA") is a smaller version of UDMA, whose object-file size is only 2048 bytes by omitting some load-time messages and the disk read speed and verify test.
UDMA and UDMAJR also include a full set of driver return codes, to show the exact cause of any error.
UDMA mode is set to the highest common mode, supported by your disk and chipset.

 UDMA - Glossary - CNET.com   (Site not responding. Last check: 2007-10-25)
UDMA defines a new protocol for the interface between the hard drive and the computer.
For users to take advantage of UDMA, both their system and hard drive must support the protocol.
UDMA retains backwards compatibility for previously existing hardware.

 Ars Technica: Unleach UDMA Love under NT - (11/98)   (Site not responding. Last check: 2007-10-25)
We've gotta shed some light on this UDMA thing.
Most importantly: understand that UDMA can only be enabled on a per-chain basis.
See, although dmacheck.exe may report that UDMA is enabled, it's not necessarily working.

 Benchtest.Com - NT4 UDMA
For the NT UDMA tests, I have decided to just clean up the text and charts a bit and leave the information as it was on the previous site.
While waiting for the introduction of Service Pack 4 with the anticipated NT 4 UDMA drivers, there are a few choices available to increase the transfer rate of your UDMA capable disk drives.
To add to the confusion as I looked for information on this subject, there were the usual well meaning, but inaccurate posts that appear in some of the newsgroups and bulletin boards.

 UDMA IDE Modes
In addition to speed improvements UDMA provides new data integrity capabilities to the EIDE interface with improved timing margins and the use of Cyclical Redundancy Check (CRC), a data transfer error detection code which helps to ensure data integrity.
Ultra DMA/33 mode 2 or UDMA mode 2 are just different ways of describing the same mode, the difference appears to be just terminology.
UDMA may also be found to be described as Ultra ATA or Fast ATA-2

 Linuxbroker - /howtoreader.shtml?file=Ultra-DMA.html   (Site not responding. Last check: 2007-10-25)
UDMA is a more advanced technology which provides for even faster throughput, up to 33.3 MB/s in UDMA mode 2 and 66.7 MB/s in UDMA mode 4, twice to four times that of EIDE, for much lower prices than SCSI.
Since all UDMA drives are fully EIDE backward-compatible, just plunk your drive on your EIDE interface like it was any old hard drive and Linux should have no problems detecting or using it.
In addition, certain UDMA interfaces that are add-in cards rather than built into the motherboard require either a patch or some trickery to use on older kernels.

 Benchtest.Com - Win98 UDMA
Before Win98 was publicly released, there was, as usual, some debate on whether 98 supported UDMA natively.
This would seem to indicate that, for whatever UDMA is ultimately worth, it is being enabled.
Definitely not the theoretical 33 MB per second that is so widely advertised, but better than the 12 MB per second without the DMA check boxes enabled.
