NEC PowerMate VT 300i Series Release Notes A-9
This completes the OS Restore (or “Fix OS”) procedure. The system is now in a
state where data can be backed up. System settings previously located in the
C:\WINDOWS directory are now in a backup directory C:\WINDOWS.ORG.
!
CAUTION
Some or all applications might not exhibit full functionality
after the Fix OS is performed. To restore the system to its
factory-installed state, perform another OS Restore using
the
Auto
or
Custom
option.
!
CAUTION
Using the
Fix OS
option repetitively without using the
Auto
or
Custom
option afterward might cause unpredictable
results.
To restore the system to its factory-installed state, perform another NEC OS
Restore using the
Auto
or
Custom
option (see “Launching the OS Restore CD”
in Chapter 3 of the PowerMate VT 300i Series User’s Guide).
PIIX4 Limitations
The following operating limitations apply to PIIX4 (PCI ISA IDE Xcelerator).
Reconfiguring Ultra DMA Support
The PCI IDE interface on the PowerMate VT 300i Series system supports the
latest ATA ULTRA DMA/33 interface. In order to do so, the PIIX4 component
that was recently released from Intel Corporation was incorporated in the
system. However, standard versions of Windows
®
95 were released prior to the
release of PIIX4; these versions do not recognize the PIIX4 as capable of
supporting ULTRA DMA/33.
Several information files (.INF files) need to be added to standard versions of
Windows 95 so the operating system can incorporate PIIX4 features. NEC CSD
already includes these .INF files in the preinstalled software that comes with
your system. NEC CSD recommends that customers use the version of
Windows 95 that is included with their system.
Note:
NEC CSD recommends that customers use the
version of Windows 95 that is included with their system
because this version is already configured for Ultra DMA/33.
