These parameters define the CardBus or PCI-to-PCI bridge memory filter base

and limit (or size) both memory filters (prefetcheable and non-prefetcheable).

The CardBus base and size values should have 4K alignments according to

Yenta specification and limit (maximum address) should be aligned to 4K

minus one.

Following formats could be used to specify bridge memory filter ranges:

BaseAddress:Limit. This means that we define the first and exactly the last

integer number in a range (e.g., 0xA0000000:0xA0000FFF specifies 4K

ranges). If you wish to disable positive decoding of PCI-to-PCI bridge's filter

range, please specify something like: 200000:1fffff.

If you prefer to specify filter size rather than filter max address you should use

BaseAddress,Size format, where Size by default is a literal decimal number. In

this case you also could use 'M' or 'K' postfixes (e.g., 0xA0000000,1M specifies

1M memory filter starting at 0xA0000000 address).

Attention! All values are treated as hexadecimal even if there is no “0x” prefix.

Examples:

MemFilter0=A0000000h:A0000fffh 4K memory range

MemFilter0=A0000000h,4K 4K memory range

MemFilter0=A1000000h:A1001fffh,Pre 8K pref. memory

MemFilter0=A1000000h,8K,Pre 8K pref. memory

This is the bridge I/O range base and limit (or size). For CardBus base and size

values must have double-word alignment.

Examples:

IoFilter = 0xD000:0xD00F 16-bytes I/O range

CardBus interrupt line settings. According to PC/AT architecture this value

must not exceed 15.

IRQ = 10 10th interrupt

Control setting of ISA Enable bit in Bridge Control Register. Valid values are 0

and 1.

Example:

ISAEnabe = 1 Set ISA Enable bit
