UIDE 參 數
UIDE usually needs only its /Sn size switch and /D: to specify a device
name for the SHCDX33C CD-ROM Redirector. UIDE 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.
/B Requests the "basic" stand-alone UltraDMA driver for disks or
CD/DVD drives (no cache nor diskettes). This may help in
running diagnostics or tests.
/D: Specifies the desired device name, used by SHCDX33C 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.
/L Requests the "large" 3.5K upper-memory driver for cache sizes
below 200-MB. If /L is omitted, the "small" 1.75K driver
is used for caches below 200-MB. /L puts more of UIDE in
upper-memory, so UIDE can still load if the HMA is "full"!
/N1 Requests NO handling of any hard-disk drives.
/N2 Requests NO handling of any CD or DVD drives.
/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.
/Sn Specifies a cache size in Megabytes of XMS memory as follows:
/S15 15-MB cache, 1920-byte table size, 16K blocks.
/S40 40-MB cache, 2560-byte table size, 32K blocks.
/S80 80-MB cache, 2560-byte table size, 64K blocks.
. . .
. thru . . (32 bytes per MB)
. . .
/S511 511-MB cache, 16352-byte table size, 64K blocks.
Values for /S may be 15, 40, or any number from 80 to 511.
If /S is omitted or invalid, an 80-MB cache is used as the
default. Use as much cache memory as possible, for best
handling of today's BIG data files --
With 128-MB memory: Use /S40 or /S80
With 256-MB memory: Use /S80 up to /S127
With 512-MB memory: Use /S160 up to /S255
With 1-GB memory or more: Use /S320 up to /S511
For more about UIDE and cache sizes, see section 7 below.
/UX Disables all CD/DVD UltraDMA, even for drives that can do it.
PIO-mode is then used on all CD/DVD requests. Except for
some "unusual" drives by Sony, etc. that do not follow all
ATAPI "rules", /UX is rarely needed. /UX does not affect
hard-disks.
