System generates a BIOS message but locks up when
booting from SSD0
1. Remove the jumper from the “S” position at W1 and reboot. When PICO
FA prompts you, select SSD0 as the first drive and SSD2 as the second
drive.
2. Display the directory of SSD0 and verify that all the necessary boot files
exist. Copy any missing files to SSD0.
3. If no files are missing, remake SSD0 to overwrite any files which may
have become corrupted. In addition, you may want to do a PFORMAT
and SYS to SSD0.
PICO FA reports a drive, but issuing a DIR generates an
error message
1. The SSD may not be formatted. Run either of the following:
PFORMAT H n
or
PFORMAT H n /m
where n represents the hard drive number.
For more information, see the Save and run programs chapter.
PICO FA does not report the drive
1. Run SETSSD and make sure it is correct.
2. Make sure that the “X” position at W1 is jumpered or that PICOFA.SYS
is in your CONFIG.SYS file of your floppy hard drive.
3. Install a jumper on the “S” position at W1.
4. Reboot your system.
System locks up on powerup; may or may not respond to
reset switch
A common cause is using a non-Octagon power supply such as a PC
desktop supply. Most of these PC supplies are rated at 5V at 20A or
more. Switching supplies usually requires a 20% load to operate prop-
erly, that is, 4A or more. Since a typical Micro PC system takes less
than 2A, the supply does not regulate properly. Output drift up to 6-7V
and/or 7-8 voltage spikes have been reported. If the power supply comes
up slowly (that is, longer than 50 ms), the sequencing of ICs on the
board may be out of sync, thus, causing the system to lock up.
