Chapter 8: External drives

Description

The XE–700 SBC is compatible with any standard floppy drive, and any IDE hard
drive that has a 16-bit IDE interface. This includes CD-ROMs, CompactFlashes,
and other IDE-compatible drives. The BIOS supports all IDE devices so no
additional software is needed.
Note The BIOS supports three IDE devices (which includes a CompactFlash),
and one floppy drive.

Hard disk controller

The XE–700 SBC supports three 16-bit IDE devices. Since the CompactFlash is
connected to the primary IDE channel with a dedicated IDE controller, additional
IDE devices connected through J4 will be secondary IDE devices (master and
slave).
Standard IDE devices such as hard drives and CD-ROM drives are interfaced via a
44-pin connector at J4. For those IDE devices that use a 40-pin interface, use the
Octagon Systems IDE cable, #4080 or #6246.
IDE combinations:
2 hard drives
1 hard drive and 1 CD-ROM drive
2 CD-ROM drives
CompactFlash and any of the above combinations

Master/slave designation for IDE devices

IDE devices have a jumper or a switch that designates whether the device is a
master or a slave device. If only one device is connected to a port, it must be
configured as a master. If two devices are connected, one must be configured as a
master and one as a slave. The XE–700 does not use the CS signal (Cable Select) to
designate master or slave on a multi-connector cable. You can use BIOS Setup to
designate either the master or the slave as a boot device.
