The EIDE disk drives work fine with FreeBSD, and you generally get significant
performance benefits.  The IDE CDROM code is green, and the IDE tape code
is AFAIK non-existent.  I personally use 540MByte, 1.6GByte and 2.5GByte
EIDE drives on my ASUS TP4N MB, with performance of 2MBytes/sec up to 9MBytes
per second depending on drive, etc...

IDE interface on the ASUS motherboard is EIDE, and the motherboard is really
nice.  It appears to be quite compatible with FreeBSD.
