This bulletin replaces Service Bulletin FA2i-017D
General Information
This service bulletin provides information on the release of a new BIOS program, a new CPU
P/N, new application software, and a new DST Disk.
Changes to BIOS, CPU, Application Software and DST Software
The BIOS chip used on CPU P/N 51477 is no longer available. The new BIOS chip required
changes to the BIOS programming, resulting in a new BIOS settings disk P/N 56280. The
CMOS password remains unchanged. BIOS Ver. 2.0 contains a new Flash Utility (8.53) and
will now overwrite the old BIOS.
In some instances, use of the BIOS disk Ver. 2.0 will result in failure. An “Interrupt Divide By
Zero “ error will be displayed. To overcome this problem you must enter the BIOS utility and
proceed to the PERIPHREAL SETUP menu. The last item on the menu ON-BOARD IDE must
be set to DISABLE. Save and exit the BIOS. Run the BIOS Ver. 2.0 loading utility P/N 56280.
The BIOS loader will set all BIOS settings to the correct choices.
BIOS related changes also required a change to P/N 51477 CPU. The currently used HFA2i CPU
board P/N 55392 will have the new BIOS chip and BIOS programming installed.
With changes to the BIOS code and CPU, extraneous characters or mysterious screen selections
may appear while using the revision 3.2 or lower revision application software or the DST. To
correct this problem, the 3.4 revision of HFA 2i software (P/N 55727) and DST P/N 55744 were
created. See service bulletin HFA2i-005D for more information concerning the software
changes. The compatibility matrix is shown in Table 1.
