• Memory Information indicates the amount of installed memory
detected in your computer, the computer memory speed, the amount
of video memory, and the size of the display cache. After you add
memory, check this option to confirm that the new memory is installed
correctly and is recognized by the computer.
• PCI IRQ Assignment specifies which IRQ lines are assigned to the
Peripheral Component Interconnect (PCI) devices installed in the
computer. Press <Enter> to configure these devices. Then select the
device whose IRQ line you want to change, and press the plus (+) or
minus (–) key to scroll through the available IRQ lines. Normally you
do not need to change the IRQ lines assigned to PCI devices unless a
particular device, device driver, or operating system requires a specific
IRQ line already in use by a PCI device.
• Primary Drive n and Secondary Drive n
Primary Drive n identifies drives attached to the primary EIDE
interface connector (labeled "IDE1") on the system board; Secondary
Drive n identifies drives connected to the secondary EIDE interface
connector (labeled "IDE2"). Use the secondary EIDE interface
connector for EIDE CD drives and EIDE tape drives.
NOTE: For all devices obtained from Dell that use the integrated EIDE
controller, set the appropriate Drive option to Auto.
NOTE: You must have an EIDE device connected to the primary EIDE
interface if you have an EIDE device connected to the secondary EIDE
interface.
The following settings identify the type of EIDE devices installed in the
computer:
– Auto (use this setting for all EIDE devices from Dell)
– Off
To choose a setting for each option, press <Enter> to access the field's
pop-up settings menu. Then type characters from the keyboard or press the
left- or right-arrow key to cycle through the settings.
