Programming the Flash EPROM,
Before Beginning Flash Programming
Perform the following steps before programming the Flash EPROM.
Step
1 Turn system power off.
2 Place a Shorting Link on J2.
3 Place the floppy disk that has the latest S68P.ROM BIOS file in
floppy drive A:.
4 Make sure that the system has a speaker that is connected.
5 Turn system power on.
Sequence of Operation and Standard Beeps
During normal operation, the Boot Block code produces a series of beeps, keyed to the operation of the Boot Block Code.
The Boot Block code beeps to:
• signify completion of a step (as shown on the previous page), and
• when there is an error.
The following table lists the sequence of operation and the expected behavior of the Boot Block Code.
Step
1 Look for the floppy disk.
2 Look for S68P.ROM on
the floppy disk.
3 Read the floppy disk.
4 Check for BIOS file size.
5 Check for Flash
EPROM.
6 Erase the Flash
EPROM.
7 Program the Flash
EPROM.
8 Continue programming
the Flash EPROM.
9 Boot Block BIOS resets
the CPU.
10 Manually reboot the
system.

Expected behavior
The system beeps one time before the BIOS attempts to
read from floppy drive A:.
The BIOS searches for S68P.ROM in the root directory of
the floppy disk in drive A:. It does not beep if this step is
completed successfully.
The BIOS reads the floppy disk. It does not beep if this step
is completed successfully.
The BIOS checks the BIOS file size. It does not beep if this
step is completed successfully.
The BIOS looks for an Intel i28F001BX-T Flash EPROM. It
does not beep if this step is completed successfully.
Two beeps sound when the BIOS begins erasing the Flash
EPROM.
Three beeps sound when the Boot Block Code begins
reprogramming the the Flash EPROM.
Four beeps sound when reprogramming has been
successfully completed.
A CPU reset is generated (the system reboots). Make sure
you remove the shorting link from J2 at this point.
Reboot the system.
