  1. Buongiorno a tutti, mi sono imbattuto in rete in un thread relativo al PMC per Z390 che adesso supporta NVRAM nativa grazie a questo aggiornamento e grazie, a quanto ho capito, agli ultimi BIOS. La domanda è: Qual è la differenza tra: * Original Table Header: * Signature "SSDT" * Length 0x0000008F (143) * Revision 0x02 * Checksum 0x2C * OEM ID "ACDT" * OEM Table ID "PMCR" * OEM Revision 0x00001000 (4096) * Compiler ID "INTL" * Compiler Version 0x20200110 (538968336) */ DefinitionBlock ("", "SSDT", 2, "ACDT", "PMCR", 0x00001000) { External (_SB_.PCI0.LPCB, DeviceObj) // (from opcode) Scope (_SB.PCI0.LPCB) { Device (PMCR) { Name (_HID, EisaId ("APP9876")) // _HID: Hardware ID Method (_STA, 0, NotSerialized) // _STA: Status { If (_OSI ("Darwin")) { Return (0x0B) } Else { Return (Zero) } } Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { Memory32Fixed (ReadWrite, 0xFE000000, // Address Base 0x00010000, // Address Length ) }) } } } e * Original Table Header: * Signature "SSDT" * Length 0x000000C6 (198) * Revision 0x02 * Checksum 0xC2 * OEM ID "ACDT" * OEM Table ID "PM" * OEM Revision 0x00001000 (4096) * Compiler ID "INTL" * Compiler Version 0x20180427 (538444839) */ DefinitionBlock ("", "SSDT", 2, "ACDT", "PM", 0x00001000) { External (_SB_.PCI0.LPCB, DeviceObj) // (from opcode) External (_SB_.PCI0.PMCR, DeviceObj) // (from opcode) Device (PPMC) { Name (_ADR, 0x001F0002) // _ADR: Address OperationRegion (PMCB, PCI_Config, Zero, 0x0100) Field (PMCB, AnyAcc, NoLock, Preserve) { VDID, 32, Offset (0x40), Offset (0x41), ACBA, 8, Offset (0x48), , 12, PWBA, 20 } } Scope (_SB.PCI0.LPCB) { Device (PMCR) { Name (_HID, EisaId ("APP9876")) // _HID: Hardware ID Name (_STA, 0x0B) // _STA: Status Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { Memory32Fixed (ReadWrite, 0xFE000000, // Address Base 0x00010000, // Address Length ) }) } } } Ho studiato il codice e vedo che una fa riferimento a PMCR e una a PM però non sono abbastanza esperto per capire fino in fondo le differenze. Qualunque risposta sarà ben accetta, so che la questione è molto "tecnica" ma mi affascina tantissimo 👾. Grazie, K.
