Field Value Comment Firmware 2 This table contains two firmware resource entries. Resource Count Firmware 2 This table allocation contains enough space to describe a maximum of two resources. Resource Maximum Firmware 1 The firmware resource entry format version Resource this table uses is 1. Version Firmware Firmware Resource Entry 0 Resource Entry Array Firmware {SYSTEM_FIRMWARE} This GUID identifies the system firmware for update via PnP. Class Firmware 1 System firmware type is 1. Type Firmware 2 The current system firmware version is 2. Version Lowest 2 Change the lowest supported firmware version to 2, so that the firmware cannot be Supported to a version earlier than version 2. This Firmware value is typically changed when the firmware Version update contains security fixes. Capsule 0 System firmware doesn’t define any private capsule update flags. Flags Last 2 The last system firmware version for which Attempt an update was attempted was 2. Version Last Attempt 0 The last system firmware update attempt was Status successful. Firmware Resource Entry 1 Firmware {DEVICE_FIRMWARE} This GUID identifies the device firmware for update via PnP. Class Firmware 2 Device firmware type is 2. Type Firmware 1 The current device firmware version is 1. Version Lowest 1 Keep the lowest supported firmware version as 1. The firmware can be rolled-back to version Supported
