Diagnostic Mode
The diagnostic mode of the NETIPC can be entered by setting the start-up pins of the keyboard
connector to the „diagnostic mode“ (see NETIPC manual) and resetting. In diagnostic mode
special code may be executed for factory diagnostics.

ROM Disk
4.4.1.
General Information
The ROM disk is a binary image (sector by sector) of a real floppy disk that is located
anywhere in the protected mode address space of the NETIPC processor. If the BIOS is
configured to support the ROM disk, it treats it like a floppy drive A:, allowing booting of the
operating system out of the ROM disk.
4.4.2.
Make a 704kB ROM-Disk Image
On delivery the BIOS is configured to support a ROM disk located at address 3f00000h with a
maximum size of 704 kbyte. The binary image is generated using a DOS batch file
'MAKEDRVX.BAT' located in directory C:\FBCUBE\NETIPCFW\EDOSROM (for
Embedded DOS-ROM), C:\FBCUBE\NETIPCFW\MSDOS (for MS-DOS) and
C:\FBCUBE\NETIPCFW\NONDOSOS (for non-DOS operating systems). These batch files
contain the following steps:
1. First an empty diskette image is created with the maximum allowable size (e.g.
704 kbytes).
2. Secondly the system files, utilities and predefined application programs are
copied into the disk image using a disk imaging tool located in directory
C:\FBCUBE\NETIPCFW\UTIL
To make the ROM-Disk image, please proceed as follows:
1. Edit the command file MAKEDRVX.BAT to include your applications programs.
Note:
in the command file delivered, the monitor program CUBMON.EXE is
included. CUBMON is part of the CUB/IOCOMSW-1A software package which
must be installed before using MAKEDRVX.BAT in order to use the program.
CUBMON.EXE may be deleted from the MAKEDRVX.BAT if not required.
WARNING
: do not delete the DOS.SYS, IO.SYS, MSDOS.SYS,
COMMAND.COM, CONFIG.SYS and AUTOEXEC.BAT entries from
MAKEDRVX.BAT!
2. Save MAKEDRVX.BAT
3. Start MAKEDRVX.BAT (Enter
C:\FBCUBE\NETIPCFW\EDOSROM>MAKEDRVX
4. Note that no error messages are allowed during the process of ROM-drive image
generation (please observe the running output on your screen carefully).
4.4.3.
Make a 1.44MB ROM-Disk Image
On delivery the BIOS is configured to support a ROM disk located at address 3f00000h with a
maximum size of 704 kbyte. Some NETIPC boards (e.g. IPC/NETIPC-2A,-3A,-5A) support a
full 1.44 MByte ROM-Disk Image.
