PCI Bus configuration (64,128,256 PCI Buses)
Hello
It seems that "PCI bus configuration" disappear from BIOS in the last DELL PRECISION T7910, T5810, T3620 and also on OPTIPLEX 7020
I need to have "256 PCI Buses".
How can I do ?
Thank You
Regards

Those are not UEFI settings. That is from CSM BIOS. The T5600 sports two PCI Express 3.0 x16 slots, one PCI Express 3.0 x4 slot, one PCI Express 2.0 x4 slot, one PCI Express 2.0 x1 slot and one legacy PCI slot. New systems do not have a legacy Slot and may not have PCI express 2.0 support.

Hello
Thanks for your answer.
Here is a copy of the Bios of a PRECISION T5600. The configuration is possible.
This possibility disappears in the last version of DELL PRECISION

No such thing. 64, 128, 256, 384, 512 bits is based on the chipset of the video card. UEFI is not the same as Legacy Bios. That setting is to allow more memory space for 32 bit os and Legacy cards.
Newer systems do not support the OLD pci-e 1.0 and 2.0 cards.
