IDE Interface
Connection
to
IDE
accomplished when using the WinSystems adapter cable, part number
CBL-126-9, connected to J6. This cable allows for the attachment of one standard 40-
pin IDE device. Configuration of any IDE device is accomplished using the Phoenix
BIOS setup menus.
The pin definitions for the 40-pin IDE
connector are:
An IDE Status LED, D1, provides visual status during IDE data transfer.
DiskOnChip Configuration
the M-Systems DiskOnChip (DOC) flash devices (www.m-sys.com). These devices are
available in sizes ranging from 8Mbytes to the currently available maximum size of
288Mbytes.
These devices are inherently supported by the VIOS and DOS (they
appear as hard disk to DOS) and are supported by a variety of other operating
systems.
Current non DOS driver support is available directly from the M-Systems
website.
The DOC device is ordinarily used in systems without an actual hard disk. In these
cases the hard drive settings for both the C: and D: drives should be set to NONE in
the CMOS Setup Menus.
partitioning and formatting software may be used to prepare it to boot. The boot-up
time may be dramatically improved by disabling the SC520 IDE controllers in the
CMOS setup when an actual hard disk will not be connected.
When the DOC is used in conjunction with an actual hard disk it automatically becomes
the secondary of D: drive. This can be useful when it is desired to load a DOC with a
large number of files that may currently reside on the hard disk. This characteristic of
becoming a secondary drive to an actual hard disk is referred to by M-Systems as
"Last Drive". This characteristic may be altered such that the DOC will become the
primary drive (or First Drive) by using the DFORMAT utility available from M-Systems.
In this case it is possible to boot from the DOC and access the hard disk as the D:
drive.
Refer to the utilities documentation accompanying the download from M-
Systems for more information if this mode is required.
