Ethernet Port Booting Priority

The order in which the BIOS detects the Ethernet ports during boot time, and the
corresponding drivers that control those ports, are listed below:
1. NET 0 (INTEL NIC 0)
2. NET 1 (INTEL NIC 1)
3. NET 2 (INTEL NIC 2)
4. NET 3 (INTEL NIC 3)
2.5.1.6

Hardware Prefetchers

Hardware prefetchers work well in workloads that traverse array and other regular
data structures. The hardware prefetcher option is disabled by default and should be
disabled when running applications that perform aggressive software prefetching or
for workloads with limited cache. For example, memory-intensive applications with
high bus utilization could see a performance degradation if hardware prefetching is
enabled.
