When the system is booted, it looks for the sbus-probe-list, which determines the order in which the SBus devices are addressed. For the SPARCstation 10, SBus address f is reserved for the CPU and should always be the first address in the sbus-probe-list.
To determine the system information and sbus-probe-list, type:
% eeprom . . . sbus-probe-list=0123 . .
The addressing numbers are 0, 1, 2, and 3. However, 0 is reserved for the CPU and should always be the first address in the sbus-probe-list for all SPARCstation systems except the SPARCstation 10 system.
The following system information and sbus-probe-list (starting with f) will be displayed if you have a SPARCstation 10 system:
% eeprom . . . sbus-probe-list=f0123 . .
