IPC/NETIPCFW-1A: User Documentation
DOC/NETIPCFW-E; V3.0
Menu Memory Configuration:
Allows setting of the chip select logic on the NETIPC module. The maximum main memory
size depends on the NETIPC board type set in the Board Type menu.
For all NETIPC but the NETIPC-5A the graphics frame buffer memory (1...4MByte) is
subtracted from the main memory (Unified Memory Architecture).
Menu ROM Shadowing:
Allows shadowing of the onboard FlashROM for faster code execution. Note that enabling
Read and Write shadowing also allows modification of the shadowed code!
Menu Drive Assignment:
Allows assignment of the available drives (ROM drive, IDE drives, etc.) to the drive letters A:
to F:.
'ROM Drive 704 k' selects image start address at 3f00000h (max. size 704 kbytes), 'ROM
Drive 1.44 M' selects image start address at 3e00000h (max. size 1.44 MBytes).
Note: The ROM drive should not be assigned to any drive letter when using Windows
95/98/NT/2000/XP on the NETIPC. Windows does not support the BIOS built in protected
mode ROM driver.
Menu IDE Configuration:
Allows setting of IDE drive parameters. The BIOS supports four IDE drives attached to the
primary (onboard) and secondary (offboard) IDE controllers. The following options are
supported:
– No IDE drive
– Autodetection (physical geometry)
Recommended for drives with less than 512 Mbyte capacity
– Autodetection (with LBA translation)
Recommended for drives with more than 512Mbyte capacity
Autodetection (with CHS translation)
–
not recommended
Note: It is very important that always the same autodetection mechanism is used which was
used to partition the drive. Otherwise all data on the drive may be corrupted due to
incompatibilities between the translation methods.
Some operating systems use LBA translation per default also for drives with less than 512
Mbyte (e.g. Windows NT). So the BIOS must be configured for this mode if the drive was
partitioned by such an operating system.
The fastest supported IDE PIO mode for the onboard primary IDE master and slave drive is
autodetected.
