You must reboot your system for the new registry setting to take effect.
To reset the guaranteed number of concurrent I/Os to the default of 32,
follow the instructions above, except use
SYMDEFIO.REG as the data file.
5.4.3 Auto Request Sense
Enabling and Disabling Auto Request Sense is found in Section 5.5,
“Troubleshooting.”
5.4.4 Disk Mirroring
This section applies only to Intel x86 platforms where the SDMS 4.XX
PCI SCSI BIOS is used.
The SDMS 4.XX PCI SCSI BIOS loads only one image into system
memory at boot time regardless of how many host adapters are used in
the system. All of the disk drives on all host adapters are recognized
through the INT13h function call. Due to this implementation, disk
mirroring under Windows 2000 could be done if it is desired. Disk
mirroring allows booting from the mirrored partition in case the primary
partition fails.
Note: These instructions may be different from Microsoft
documentation.
To create a Windows 2000 Fault Tolerant (FT) diskette, follow these
instructions:
Step 1. Format a diskette in drive A: by using Windows 2000 (Windows
Explorer or My Computer) for use as a FT boot floppy.
Step 2. From the root directory of the primary partition, copy NTLDR,
NTDETECT.COM , and BOOT.INI to this diskette.
Step 3. Temporarily remove the read only attribute of the BOOT.INI file
so that it can be modified and saved.
Step 4. Edit the BOOT.INI file on the FT diskette and modify the
following line where you want to boot the mirrored partition:
multi(0)disk(0)rdisk(x)partition(y)\
where multi(0) and disk(0) should always remain the same.
X = the drive number of the mirrored partition in the INT13h
chain minus 80h.
