14. FLASH FILE SYSTEM
II
14.1 INTRODUCTION
With FLASH FILE SYSTEM II, a read/write MS-Flash partition can be created in the 2MB
or 4MB Flash EPROM device. Such a partition can be accessed via the DOS commands.
Section 12 - VFLASH Software - explains how a read-only Flash partition is created with
VFLASH and how data can be stored in files with the VFLASH Transfer Utility.
The 2MB or 4MB user or data Flash device can be configured in one of four ways:
1. As one read-only partition, created by VFLASH. This partition can be created as a
bootable or non-bootable disk. See Section 12 for more information.
2. As one read/write MS-Flash partition created by FLASH FILE SYSTEM II.
3. As a combination of the above two: one read-only VFLASH partition, followed by one
MS-Flash read/write partition. The system will set up both as a different drive, with the
MS-Flash disk always the last. For example, VIP-UP can set up the VFLASH disk as
“Installed Bootable” (C:), other physical hard disks as D: and E:, while the MS-Flash
disk, in this case, would automatically be set up as the next drive letter, that is F:.
Another example could be only one hard disk, with the following setup: hard disk (C:),
VFLASH disk “Installed” (D:) and MS-Flash disk (E:).
4. The fourth possible configuration is similar to the previous one except that space (one or
more memory blocks) is left between the VFLASH disk and the MS-Flash disk. This
non-partitioned space can be used by special applications to store data; this can only be
done safely if one knows the exact address of these memory blocks.
FLASH FILE SYSTEM II can be purchased from TEKNOR and is not part of the standard
package and utilities.
