Address Decode Enable. Bit 0 can only be enabled from the serial EEPROM.
To disable, set the PCI Expansion ROM Address Decode Enable bit to 0
(PCIERBAR[0]=0).
Reserved.
Specifies which PCI Address bits to use for decoding a PCI-to-Local Bus
Expansion ROM. Each bit corresponds to a PCI Address bit. Bit 27
corresponds to address bit 27. Write 1 to all bits that are to be included
in decode and 0 to all others (used in conjunction with PCIERBAR). Default is
64 KB; minimum range, if enabled, is 2 KB, and maximum range allowed by
PCI r2.2 is 16 MB.
Note:
value” is two’s complement of range.
EROMRR should normally be programmed by way of the serial EEPROM
to a value of 0h, unless Expansion ROM is present on the Local Bus. If the
value is not 0h (default value is 64 KB), system BIOS may attempt to allocate
Expansion ROM address space and then access it at the local base address
specified in EROMBA (default value is 1 MB) to determine whether the
Expansion ROM image is valid. If the image is not valid, as defined in Section
6.3.1.1 (PCI Expansion ROM Header Format) of PCI r2.2, the system BIOS
unmaps the Expansion ROM address space it initially allocated, by writing 0h
to PCIERBAR[31:0].
Reserved. (PCI Address bits [31:28] are always included in decoding.)
Range (not Range register) must be power of 2. “Range register
