PCI Parity Checking
This setting controls PCI parity checking at the PCI bridge chip. Parity checking is
performed if enabled and ignored if disabled. The default is disabled. Certain PCI
adapters have been known to generate bad parity on the PCI under certain loading
conditions, which results in system errors. Ensure that your specific PCI configuration will
operate correctly prior to turning on parity checking.
Extended Memory Test
Extended memory test can be enabled or disabled. When enabled, the memory test writes
and then reads several patterns of data to main memory. This testing verifies the integrity
of the memory.
Password Setup
To help maintain system security, AlphaBIOS provides two levels of password protection:
system setup and system startup. When system setup protection is enabled, you need a
password to enter the AlphaBIOS setup program. When system startup protection is
enabled, you must enter a password before system initialization will take place. Startup
password protection provides more comprehensive protection than setup password
protection because the system cannot be used until you enter the correct password.
