We have a few SYS-6019U-TN4R4T systems, and we try to set the MMIO settings in the BIOS to work with our PCI-e cards that we are working on. Can you tell me what these settings meant?
Above 4G: Enabled/Disabled
MMIO high base:
MMIO High Granularity size:
1) Above 4G: Enable this setting mean you tell BIOS to enable the 64-bit PCIe I/O addressing.
2) MMIO high base: You tell the BIOS to configure the PCIe device at the high base region by specifying the starting addresses like 56T, 40T etc.
3) MMIO High Granularity size: You specify the size limit of the PCIe device can use.
