Reserved.
IO_ENABLE_SIO_IR (Enable Integrated SIO Infrared).
0: Disable.
1: Enable.
IO_SIOCFG_IN (Integrated SIO Input Configuration). These two bits can be used to disable the integrated SIO totally or
limit/control the base address.
00: Integrated SIO disable.
01: Integrated SIO configuration access disable.
10: Integrated SIO base address 02Eh/02Fh enable.
11: Integrated SIO base address 015Ch/015Dh enable.
IO_ENABLE_SIO_DRIVING_ISA_BUS (Enable Integrated SIO ISA Bus Control). Allow the integrated SIO to drive the
internal ISA bus.
0: Disable.
1: Enable. (Default)
Reserved. Set to 0.
IO_USB_SMI_PWM_EN (USB Internal SMI). Route USB-generated SMI to SMI Status Register in F1BAR0+I/O Offset
00h/02h[14].
0: Disable.
1: Enable.
IO_USB_SMI_EN (USB SMI Configuration). Allow USB-generated SMIs.
0: Disable.
1: Enable.
If bits 19 and 20 are enabled, the SMI generated by the USB is reported via the Top Level SMI status register at F1BAR0+I/
O Offset 00h/02h[14].
If only bit 19 is enabled, the USB can generate an SMI but there is no status reporting.
IO_USB_PCI_EN (USB). Enables USB ports.
0: Disable.
1: Enable.
Reserved.
