APPENDIX D − BIOS RECOVERY
The Classic/PCI i486 Baby-AT incorporates an AMI system BIOS on a FLASH component. FLASH BIOS allows easy
upgrades without the need to replace an EPROM. The upgrade utility fits on a floppy diskette and provides the
capability to save, verify, and update the system BIOS. The upgrade utility can be run from a hard drive or a network
drive, but no memory managers can be installed during upgrades.
The latest upgrade utility and BIOS code are available in the public section of the iPAN bulletin board.
USING THE UPGRADE UTILITY
If the utility is obtained from iPAN, UNZIP the archive and copy the files to a bootable MS-DOS 3.3, 4.01, 5.0, or
6.0 bootable diskette. Reboot the system with the upgrade diskette in the bootable floppy drive and follow the
directions in the easy to use menu-driven program.
RECOVERY MODE
In the unlikely event that a FLASH upgrade is interrupted catastrophically, it is possible the BIOS may be left in an
unusable state. Recovering from this condition requires the following steps (be sure a power supply has been attached
to the board, and a floppy drive is connected as drive A:):
1. Move jumper RV to the bottom position.
2. Install the bootable upgrade diskette into drive A:
3. Reboot the system.
4. Because of the small amount of code available in the non-erasable boot block area, no video is available to direct
the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED.
When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH
device. As soon as the drive LED goes off, the system can be turned off.
5. Reset jumper RV to the top position.
6. Leave the upgrade floppy in drive A: and turn the system on.
7. Continue with the original upgrade.
