Adaptec's AHA-17 40/17 44 Download utility should be used
to
perform a firmware download or to upgrade the installed micro-
code to a new revision to retrieve firmware information and
also format attached drives. This utility contains three main
features:
• Download Firmware
• Firmware Information
• Low-level Disk Format
Firmware download causes the host adapter to overwrite its
program memory with microcode supplied by the user from an
external source like the ASW-Ml 74. After the data is written to
the host adapter's internal RAM, and a successful checksum
test done by the host adapter, the host adapter will then repro-
gram its EEPROM with the new firmware. In order to change
the host adapter current interface mode, the user must reconfig-
ure the system memory by running the Configuration utility
(described above).
Firmware information is used to obtain release information and
revision level of the host adapter's firmware. Use this command
to ensure that proper firmware is loaded or to confirm the mode
in which the board is currently operating.
