Using The Fail-Safe Loader - DEC AlphaServer 1000A Owner's Manual

Using the Fail-Safe Loader

The fail-safe loader (FSL) allows you to boot an Update Utility diskette in an attempt
to repair corrupted console files that reside within the FlashROMs on the system
board. Use the FSL only when a failure at startup prevents you from accessing the
console mode and you have checked the operator control panel for progress
messages.
Using the Update Utility
To activate the fail-safe loader:
1. Turn off the system
2. Install the update utility diskette in the diskette drive.
3. Remove the top cover and side panels (See "Top Cover and Side Panels" in
Chapter 5, "Installing and Removing Components").
4. Enable the fail-safe loader by moving the J1 jumper on the CPU card from the
normal position (see Figure 8-1) to the position nearest the system board (7).
5. Replace the top cover and side panels.
6. Turn on the system, and check the operator control panel for progress messages.
Respond "yes" to the update prompt.
7. After the update utility has completed, turn off the system.
8. Remove the top and side panels.
9. Disable the fail-safe loader and set the SROM jumpers to their normal operating
position.
10. Replace the top cover and side panels, and turn the system back on.
11. Check to make sure that the appropriate console prompt appears.
