Chapter 17: Troubleshooting
If your system is not working properly, check the following items.
Boot Block Recovery
The 2060 CPU Card supports boot block recovery. This feature allows the user to
reprogram the system BIOS over COM1 using an HDC-18-SBC-Multiport cable, a
null modem adapter, a floppy disk, and a host computer. This option should only
be necessary if a BIOS has been programmed into the 2060 CPU Card and is either
corrupted or non-bootable. For more information covering the boot block recovery
process read the Boot block recovery section in chapter 16 and call Octagon
Systems Technical Support.
Memory conflicts using operating system other than DOS
If you are using an operating system other than DOS the X jumper should be
removed. The X jumper maps the INT17 extended BIOS into the 0xD8000-
0xDFFFF memory. This can cause problems with applications or hardware running
on other operating systems if they attempt to use this memory range. Removing
the X jumper frees this memory for use by other operating systems.
No system LED activity
If there is no LED activity at CR2, check the following:
Make sure all PC/104 expansion cards are removed from the 2060 CPU Card.
This ensures that other cards are not interacting with the 2060 CPU Card.
Remove the jumper from the “S” position at W1[1–2].
Check all power connections to the 2060 CPU Card card.
Measure the supply voltage at the J7 power connector and verify that the
voltage at the 2060 CPU Card card is +5V (+/–0.25V).
Make sure your power module pr5V (+/–0.25V) and at least 2.5A of
current.
No CRT or flat panel video
If the LEDs appear to be functioning properly, but there is no video activity, check
the following:
Make sure all PC/104 expansion cards are removed from the 2060 CPU Card.
This ensures that other cards are not interacting with the 2060 CPU Card.
Remove the jumper from the “S” position at W1[1–2].
If using a CRT monitor, check the cable and connections going from the J5
connector to the monitor.
