according to whether or not a jumper has been installed. Refer to the INT17 calls to
read user jumper on page 96.
BIOS recovery jumper
The BIOS recovery jumper on the 2060 is W1[9–10]. This jumper allows you to
reinstall the BIOS from a floppy disk using a serial link from COM1 of the 2060 to
COM1 of a host computer. When the BIOS recovery jumper is removed, the system
will use the boot block recovery process to program a new BIOS.
The BIOS recovery process uses the embflash.exe utility. This utility can be
obtained from Octagon Technical Support. To use the BIOS recovery jumper the
following steps must be taken:
1. Copy the EMBFLASH.EXE, PLATFORM.BIN, CLIENT.BIN, and BIOS.ROM
files to the root directory of a bootable floppy disk.
2. Remove power from the 2060.
3. Remove the W1[9–10] BIOS jumper.
4. Using a 2060 CPU Card HDC-18-SBC-Multiport cable and a null modem
adapter connect COM1 on the 2060 to COM1 on the Host computer. It does not
matter what OS is on the HOST computer as long as a DOS session can be
started.
5. Put the bootable floppy disk from step 1 with the embflash.exe and support
files in drive A of the host computer, and reboot the host computer from the
floppy drive.
6. Power up the 2060. If you have a post card, you can place it on the 2060
PC/104 or PC/104 Plus bus and the system will boot to a post A1, or you can
allow about 5 seconds for the system to boot to the boot block recovery state.
7. On the host computer type embflash<enter>. The host computer will display a
status screen that shows the progress of the BIOS programming.
8. When the status screen indicates the process is complete power down the 2060
and replace the W1[9–10] jumper. The new BIOS will now be used when the
2060 is re-started.
BIOS programming using PHLASH.EXE
The BIOS on the 2060 can be reprogrammed using the PHLASH.EXE utility. This
utility is in the Utilities zip file (see page 117). To program the new BIOS the
following steps must be taken:
1. Copy PHLASH.EXE, PLATFORM.BIN, and BIOS.ROM to the root of a
bootable DOS floppy disk.
2. Boot the 2060 from the DOS floppy disk with a CRT monitor or flat panel
connected to the system. Note that HIMEM.SYS cannot be used in
CONFIG.SYS.
3. At the DOS prompt for the “A” drive type phlash <enter>.
