Troubleshooting
Unable to boot host system on Windows or Linux
Problem:
Unable to boot the host system with the network adapter installed on Windows or Linux operating
systems.
Troubleshooting:
• Remove the network adapter and reboot. Verify that the system is able to boot without the network
adapter.
• Verify that the required minimum 2 GB of system memory per 10 Gigabit Ethernet port is installed on
the host system.
NOTE: Windows 32 bit may require the Physical Address Extension (PAE) option to utilize 4
GB or more of memory. PAE is a memory address extension that enables support of greater
than 4 GB of physical memory for most 32-bit (IA-32) Intel Pentium Pro and later platforms. For
more information, see PAE Memory and Windows information on the Microsoft
(http://www.microsoft.com
) website.

• Verify that the ROM scan is disabled in the BIOS.
• Verify that no system error messages occurred in the following:
o eventvwr.exe (Windows event viewer)
