Systems with More Than Three PCI Cards
PXE-Booting Return Error Message (6403173)
When Sun Fire X4200 servers have more than three PCI cards installed in the five
PCI slots and more than three cards are PXE booted, all four of the GB Ethernet ports
report the following error message:
Base-code ROM ID structure was not found
Analysis
This message is displayed because of the limitation on option ROM space in the
server’s BIOS.
The BIOS option ROM is 128 KB. Of these 128 KB, approximately 80 KB are used by
the VGA controller, the LSI controller, and the network interface card.
Approximately 48 KB remain for the Option ROM.
When more than three PCI cards PXE boot, more option ROM space is requested
than is available, so the PXE base code cannot be loaded.
Workaround
A maximum of three PCI cards can be PXE-booted in the server. To avoid the
Base-
code ROM ID structure was not found
message, disable option ROM on the
one or more cards that do not need option ROM to boot.
1. Enter the BIOS Setup utility by pressing the F2 key while the system is booting
up and performing POST.
2. On the BIOS Main Menu screen, select the PCIPnP tab to open the PCI/PnP
Settings screen.
3. Change the
PCIX SLOT
fields to
Disabled
for those PCI cards that will not be
PXE booted.
4. Press and release the right arrow key until the Exit menu screen is displayed.
5. Follow the instructions on the Exit menu screen to save your changes and exit the
Setup utility.
