4.5
TrueFFS the industry standard for flash disk emulation, is implemented into most major operating systems.
Proprietary operating systems are supported with the DiskOnChip SDK. The DiskOnChip software
integration is straightforward and configuration is quickly accomplished. For specific configuration
instructions, refer to documentation from M-Systems and from the relevant OS vendors.
Features

When used in PC-compatible architectures, the DiskOnChip should be allocated an 8KB memory window
in the BIOS expansion memory range, typically located between 0C8000H and 0EFFFFH. During the boot
process, the BIOS code loads the TrueFFS firmware into the PC’s memory and installs the DiskOnChip as
a disk drive in the system. When the operating system is loaded, the DiskOnChip is recognized as a
standard disk. No external software is required in order to boot from the DiskOnChip. Figure 4 illustrates
the DiskOnChip 2000 TSOP 16MB memory window in relation to the PC memory map.

Similar to other block devices, the DiskOnChip 2000 TSOP is accessed using standard file system calls.
Applications can write to and read from any sector on the DiskOnChip. The DiskOnChip is compatible
with most diagnostic utilities, applications and file systems.
TrueFFS accesses the flash memory within the DiskOnChip through an 8KB window in the CPU’s
memory space.
TrueFFS handles the paging of this window in the flash array, and provides flash disk emulation that
includes wear leveling, bad block management and retirement, and garbage collection.
