Chapter 19:
Using PICO FA
≡
Description
Phoenix’s PICO FA™ includes an extended BIOS (PICOFA.IMG), a
device driver (PICOFA.SYS), and a format utility (PFORMAT.EXE).
The extended BIOS emulates two read/write hard drives using flash
memory in SSD0 and SRAM in SSD2. The format utility
(PFORMAT.EXE) formats (or reformats) the writeable SSDs. The
device driver PFORMAT.EXE is used when booting from a floppy or
hard drive and when the extended BIOS (PICOFA.IMG) is disabled.
For more information, see the Save and run programs chapter and the
SETSSD section in the Setup programs chapter.

Using PFORMAT
Formatting a drive
To format a drive, do one of the following:
n
For unformatted or preformatted drives, enter the following
command:
PFORMAT H n [/m]
where n is the hard drive sequence number. This number includes
IDE drives and SSDs. The optional parameter /m specifies PICO FA
is to write an MBR (master boot record). This is required for
unformatted drives that are not AMD, Intel, or Sharp flash memory.
n
For preformatted drives, enter the following command:
PFORMAT D: [/m]
Making a drive bootable
To make a drive bootable, do one of the following:
n
Use SYS.EXE, which calls ROM–DOS.SYS, to make SSD0 bootable.
ROM–DOS.SYS must be on the floppy boot disk.
n
Boot from an MS-DOS operating system, if you are using MS-DOS
You must boot from a floppy or hard drive.
To add your application, copy the files required for your application to
the drive.
Note On occasion, PICO FA does a “garbage collection” of the flash file sys-
tem. You may see a performance degradation during this time.
