Register: Subsystem vendor ID
Type:
Read-only, Read/Write (when bit 5 in the system control register is 0.)
Offset:
40h (Functions 0, 1)
Default: 0000h
Description: This register, used for system and option card identification purposes, may be required for
certain operating systems. This register is read-only or read/write, depending on the setting of
bit 5 (SUBSYSRW) in the system control register. When bit 5 is 0, this register is read/write;
when bit 5 is 1, this register is read-only. The default mode is read-only.

Description: This register, used for system and option card identification purposes, may be required for
certain operating systems. This register is read-only or read/write, depending on the setting of
bit 5 (SUBSYSRW) in the system control register. When bit 5 is 0, this register is read/write;
when bit 5 is 1, this register is read-only. The default mode is read-only.
If an EEPROM is present, then the subsystem ID and subsystem vendor ID will be loaded
from EEPROM after an reset.
