SBC-GX1 Technical Manual Software support
Software support
The development kit contains a support CD that incorporates reference material and
software utilities that can be used to support the SBC-GX1. The following sections
describe the software support and provide guidelines for using the drivers supplied on
the CD.
Datalight ROM-DOS 6.22
If your SBC-GX1 board is fitted with flash memory it will be supplied with a license for
Datalight's ROM-DOS 6.22 operating system. This operating system will be pre-
installed on the flash drive.
ROM-DOS is a Microsoft MS-DOS compatible operating system that has been
specifically designed for embedded systems. The system and command files are
physically much smaller, but still provide full compatibility to allow standard DOS
applications to run without modification. ROM-DOS supports all the standard utility files
like SYS, PRINT, MODE, FDISK, FORMAT etc. These files are supplied on the support
CD and can be used as required.
A full user manual for ROM-DOS is also supplied on the CD that provides detailed
information on the operating system and supported interrupts and features.
Datalight FlashFX flash filing system
The flash memory incorporated onto the SBC-GX1 is configured as a silicon read/write
disk drive. This disk is supported using Datalight's FlashFX software. This software is
designed to enable the disk to be accessed using standard DOS routines. The FlashFX
software is installed during the POST process as a BIOS extension. This enables the
flash disk to be used as a boot disk and this will be the default boot device if a hard disk
drive is not present in the system. When shipped the flash memory is formatted and
configured as a ROM-DOS system disk.
The FlashFX software has been designed to incorporate wear levelling algorithms. The
wear levelling ensures that the flash memory is used evenly and that no one sector is
continually being written to. This maximizes the write performance of the flash device.
The support CD contains utilities that can be used to ensure that the flash disk is
configured correctly (see the README file in the FLASHFX directory on the support
CD). If the flash disk gets corrupted for any reason, these utilities can be used to
reformat the flash. The boot disk provides an automatic mechanism for reformatting the
flash memory and copying the ROM-DOS operating system.
