var OENMap = map[string][3]uint8{
	"Wiwynn": {0x0, 0x9c, 0x9c},
}

OENMap maps OEM names to a 3 byte OEM number.

OENs are typically serialized as the first 3 bytes of a request body.

Functions ¶

func CheckBMCBootOrder ¶

func CheckBMCBootOrder(i *ipmi.IPMI, bmcBootOverride bool) error

CheckBMCBootOrder synchronize BIOS's boot order with BMC's boot order. When BMC IPMI sets boot order (valid bit 1), BIOS will update VPD boot order and create new BootEntries accordingly. If BMC didn't set boot order, BIOS would set its current boot order to BMC.

func ClearCMOSClearValidBits ¶

func ClearCMOSClearValidBits(i *ipmi.IPMI, data []byte) error

Set BIOS boot order with both CMOS clear and valid bits cleared

func IsCMOSClearSet ¶

func IsCMOSClearSet(i *ipmi.IPMI) (bool, []byte, error)

Get BIOS boot order data and check if CMOS clear bit and valid bit are both set

func SendOemIpmiDimmInfo ¶

func SendOemIpmiDimmInfo(i *ipmi.IPMI, info []DimmInfo) error

func SendOemIpmiProcessorInfo ¶

func SendOemIpmiProcessorInfo(i *ipmi.IPMI, info []ProcessorInfo) error

func SetOemIpmiPostEnd ¶

func SetOemIpmiPostEnd(i *ipmi.IPMI) error
