Bit 43: X.V capable
A value of ‘1’ indicates that X.X V voltage source is available for the powering of PC cards in this
system. A value of ‘0’ indicates that X.X V voltage source is not available for the powering of PC
cards in this system.
Bit 42: Y.V capable
A value of ‘1’ indicates that Y.Y V voltage source is available for the powering of PC cards in this
system. A value of ‘0’ indicates that Y.Y V voltage source is not available for the powering of PC
cards in this system.
Bit 41: 5.0V capable
A value of ‘1’ indicates that 5.0 V voltage source is available for the powering of PC cards in this
system. A value of ‘0’ indicates that 5.0 V voltage source is not available in this system, and that
the PC card sockets only operate at other available voltages indicated by bits 43:41. Systems that
only supported 5 V cards set bit 41 to ‘1’ and clear bits 43, 42, and 40 to ‘0’.
Bit 40: 3.3V capable
A value of ‘1’ indicates that 3.3 V voltage source is available for the powering of PC cards in this
system. A value of ‘0’ indicates that 3.3 V voltage source is not available for the powering of PC
cards in this system. System designs that support both 3.3 and 5.0 V cards set bits to ‘1’ and clear
bits 43 and 42 to ‘0’.

Reserved for future use.
Bit 52 — ZV Port B Wired
A value of ‘1’ indicates that in the particular system implementation Socket B is wired for ZV
operation. A value of ‘0’ indicates that Socket B is not wired for ZV operation.
Bit 51 — ZV Port A Wired
A value of ‘1’ indicates that in the particular system implementation Socket A is wired for ZV
operation. A value of ‘0’ indicates that Socket A is not wired for ZV operation.
