Figure 4-8 B: BIOS Logo and RAM Counting
Step 3. System Configuration
The BIOS checks the E4991A configuration and displays it shown in as Figure 4-9. Three
PCI boards, A21, A25, and A26 can be confirmed like below.
• "PCI Slot 1 : Ethernet" is A25 LAN board
• "PCI Slot 2 : VGA" is A26 Display board
• "PCI Slot 3 : Unknown Device" is A21 Analog Interface board
If the BIOS couldn't detect above boards caused by hardware problem or poor connection,
nothing is displayed there. In addition, the BIOS can not check the operation of the above
boards. When nothing is displayed there, doubt first whether a PCI slot connection is poor
or not.
But A24 GPIB board can't be confirmed because it is on the ISA slots.
