Dell OptiPlex System BIOS, A07

The following changes were made in the A07 BIOS to generate the A08 BIOS:

1. Updated copyright to 1996.
2. Fixed address reported on memory errors.
3. Added a delay in ATPOST to prevent systems without hard drives from continually rebooting.
4. Attempt floppy boot before any PnP boot card.
5. Added delay in POST to keep systems with no IDE hard drives from continually rebooting.
6. Fixed problem with hitting -alt-numeric keypad enter where the system would think the control key was still down even after you released it.
7. Year 2000 code.
8. Added password status field and the ability to lock the system password.
9. Caching of BIOS F000 segment disabled to prevent system from locking on boot in compatible mode, and to allow a user to go into setup when emm386 was loaded.
