Appendix F Excluding Memory From Windows 371

Western Digital EtherCard Plus and EtherCard Plus/A

The Western Digital EtherCard Plus and EtherCard Plus/A have a

segment of shared RAM that must be excluded from use by Microsoft

Windows. The starting address of this segment is the shared RAM

address; the size of the segment is the shared RAM buffer size.

The shared RAM address for these network adapters is configured by a

line in the PROTOCOL.INI file. Edit the PROTOCOL.INI file and find

the block of lines under the [WD8003] section. Look for the keyword

RAMADDRESS (Western Digital refers to the shared RAM as the

RAM buffer address). The value after RAMADDRESS is the starting

address of shared RAM for this network adapter.

The following is an example of the lines in a PROTOCOL.INI file for a

Western Digital network adapter. In this example, the shared RAM

address is 0xD000.

The shared RAM buffer size for the EtherCard Plus is 8K (or 0x200),

and the shared RAM buffer size for the EtherCard Plus/A is 16K (or

0x400). In this example, the last address in the segment to exclude for an

EtherCard Plus would be 0xD1FF (0xD000 + 0x200 - 1). The line

needed in the SYSTEM.INI file would be:

IBM Token-Ring Network Adapter (1, 2, or A)

The IBM Token-Ring network adapters have two segments of memory

that must be excluded from use by Microsoft Windows. The first is a

segment of read-only memory (ROM); the second is a segment of shared

RAM.

The starting address for the ROM segment is set by a jumper on the

network adapter. For more information about this jumper, see the

manual for this network adapter. The size of the ROM segment is 8K (or

0x200).
