- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Is this the eight-bit version similar to what comes on-board with some boards;
- Zeos for example? What's wrong with using it if the bandwidth meets your needs?
- Hang a hard drive on it. The drive can't saturate the bandwidth.

- >> 4) Wide SCSI-II @ 40MB/sec (uses a 32 bit data path)
