I've a Dell T3610 workstation which has following CPU.
Intel(R) Xeon(R) CPU E5-1607 v2 @ 3.00GHz
I've plugged in a Broadcom XLP pcie card into PCIe Gen-3 x16 slot of this Dell machine.
In bios, I want to disable the "memory mapped IO above 4 GB" option.
When I uncheck this option, click on "Apply", exit from bios and reenter it,
I see that the "memory mapped IO above 4 GB" option is again enabled (checked).
If I remove the aforementioned pcie card, then, however, I'm able to disable
"memory mapped IO above 4 GB" option in bios.
Could someone please tell me how to disable this option with the pcie card still plugged in ?
