System Overview
Internal Disk Controllers
The M Pro system has an internal floppy controller (not discussed)
that controls a floppy drive in drive bay 4 (see Figure 2-3). Drive bay 3
might contain another floppy drive.
The remaining internal disk controller is an IDE controller with
channels 0 and 1. Both channels have the capability of having one
master device and one slave device connected, however, only one
channel has a cable connected. The cable has two connectors, one
connected to the CD-ROM in drive bay 1, and an empty connector that
you could use to connect an IDE device in drive bay 2. Drive bays 1
and 2 are 5.25-inch bays.
All internal SCSI devices are cabled from the Adaptec
™
29160LP
board, and are considered part of the 15 total available SCSI devices on
the board.
Drive bays 3 to 7 are 3.5-inch bays. Drive bay 7 contains the system
drive while drive bays 5 and 6 can connect other SCSI devices using
the same cable as the system drive.
c
Any SCSI device placed in drive bay 5 or 6 must be an Ultra3. If you
attach a single-ended fast and wide device to the internal SCSI bus,
the speed of the Adaptec 29160LP board is brought to that level.
Avid does not recommend the use of any Jaz
®
type drive on this
SCSI board.
Keyboard and Mouse
Avid replaces the standard IBM keyboard with a customized
keyboard featuring labeled keycaps for the Windows 2000 products.
The three-button IBM mouse is the standard. Avid might or might not
replace the standard mouse with a Microsoft
®
mouse for certain
products, but whatever mouse is used, it must have a PS/2-style male
connector to plug into the system.
