Bus Mastering
SF
I was told its needed for better performance.
I'm assuming most desktops can handle this?

Bus Mastering is a general technique by which controllers and cards can
transfer data between themselves and memory in the fastest possible way.
It's so-called because for the duration of transferring a block of data,
the card takes control of the bus (becomes the master), even the CPU has
lower priority than the card.
It's used for high-speed I/O such as disks mostly, and some video
capture cards and fast network cards. If you're thinking of the
bus-master drivers for hard disks, this is important with NLE in order
to get the maximum disk read/write speed. It also leaves the CPU free to
do other things while blocks of data are being transferred. Modern fast
disks can only achieve their max. performance if used with a
bus-mastering controller and driver.

Bus Mastering is a standard feature of the PCI bus, so all decent modern
motherboards support it. Windows 98 includes bus-mastering drivers for
the common chipsets, so you shouldn't need anything special. Windows 95
originally did not, although it was included in later service packs,
though I'm not quite sure when. You can download drivers for the common
chipsets.
