Setting PCI Bus Padding Options
You can disable the default PCI Bus padding where each expansion slot is provided with an extra
PCI Bus number. By default, the System BIOS pads one PCI bus per expansion slot to allow
expansion cards with PCI-PCI bridges to not effect current bus numbering schemes. Disabling this
option works around issues with certain expansion cards. It is not recommended to disable this
option unless a specific issue is encountered.
HP recommends disabling this option only when encountering a specific issue.
To set PCI Bus padding options:
1.
From the System Utilities screen, select System Configuration
→BIOS/Platform Configuration
(RBSU)
→Advanced Options→Advanced System ROM Options→PCI Bus Padding Options and
press Enter.
2. Select one of the following options:
•
Enabled (default)
•
Disabled
3. Press F10 to save your selection.
