UIDE and UIDEJR usually need only a /D: switch to specify a device name
for the SHCDX33E CD-ROM Redirector. UIDE also needs its /S switch to
specify a cache size. UIDE and UIDEJR switch options are:
/A Specifies use of ALTERNATE "legacy IDE" I-O addresses. The
first legacy controller will use alternate 01E8h/03EEh and
0168h/036Eh addresses, and a second legacy controller will
use normal 01F0h/03F6h and 0170h/0376h I-O addresses. If
/A is omitted, the first legacy controller uses normal and
the second legacy controller uses alternate addresses, the
usual case with most mainboards and BIOS programs. /A is
for "odd" cases where "legacy IDE" addresses are REVERSED.
/A does not affect "native PCI" controllers.
/D: Specifies the desired device name, used by SHCDX33E to access
the CD/DVD drives. Example: /D:CDROM1 /D:MYCDROM etc.
Device names must be from 1 to 8 bytes O.K. for use in DOS
filenames. If /D: is omitted, or the device name after a
/D: is missing or invalid, UDVD1 is used as the default.
When disks/diskettes are present but no CD/DVD drives, the
name UIDE$ or UIDEJR$ shall override any /D: name.
/Sn For UIDE only, specifies the desired cache size, in megabytes
of XMS memory. Values for /S are 5, 15, 25, 40 , 50, and
any number from 80 to 4093. /S1024 or more gives a 1- to
4-GIGABYTE cache! Use as much cache as possible, to deal
with today's BIG data files --
Below 128-MB memory: Use /S5 /S15 /S25 or /S40
With 128-MB memory: Use /S25 /S40 /S50 or /S80
With 256-MB memory: Use /S80 up to /S127
With 512-MB memory: Use /S160 up to /S255
With 1-GB memory: Use /S320 up to /S511
With 2-GB memory: Use /S640 up to /S1023
With 4-GB memory: Use /S1280 up to /S3072
Small systems may prefer /S25 or /S50 which set 1600 cache
blocks and are more efficient. If /S is omitted/invalid,
an 80-MB cache is set. Except for 25 or 50, values below
80 are "rounded" to 40- 15- or 5-MB. UIDE displays "XMS
init error" and aborts when not enough XMS memory is free!
If so, a smaller cache must be requested. For older V2.0
XMS managers (ROM-DOS etc.), only /S5 to /S50 may be used.
UIDEJR will ignore /S.
/Q Enables awaiting "data request" before starting UltraDMA disk
transfers. /Q is for "old" systems and must be used only
if UIDE loads O.K. but seems unable to transfer data. /Q
must be OMITTED with a SATA-to-IDE adapter from Sabrent or
others, as such cards do not emulate "data request" from a
SATA disk! /Q does not affect CD/DVD drives.
