|
<P>Well, there is good news and there is bad news. The good news is that a UDMA
|
|
interface can be used with both UDMA hard drives and legacy EIDE hard
|
|
drives, and will be a lot faster than an EIDE interface.
|
|
<P>The bad news is that the old stock kernels (2.0.x) do not currently
|
|
support UDMA very well. The new 2.2.x kernels do support UDMA33, however,
|
|
and kernel patches are available to add UDMA support for kernels that lack it.
|
|
<P>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. That is why
|
|
this document exists - to explain how to get the patches and work the trickery.
|
|
