Description
Subsystem ID (R: default 0001h). Allows add-in card or subsystem vendors to
put their product ID in this field. During normal operation, this register is read-
only. However, a new value can be downloaded into this field during power-up
through external serial EEPROM if it is available and valid. In addition, a write-
enable bit for this register is defined in bit 11 of local control register 6 which can
be used by the BIOS to overwrite this register for the desired subsystem ID
before the OS being loaded.
Subsystem vendor ID (R: default 134Dh). Allows add-in card or subsystem ven-
dors to put their unique ID in this field. During normal operation, this register is
read-only. However, the content of this register can be changed in several ways:
The PCT789T-A checks the availability of the external serial EEPROM during the
power-up reset period and if the data is valid, loads the configuration information
into the corresponding registers.
A write-enable bit for this register is defined in bit 1 of local control register 6, which
can be used by the BIOS to overwrite this register for the desired subsystem
vendor ID before the OS being loaded.
* Contact your PC-TEL representative for more information on subsystem
vendor ID codes.
