Target Disk Mode (sometimes referred to as TDM or Target Mode) is a boot mode unique to Macintosh computers. When a Mac that supports Target Disk Mode [1] is started with the 'T' key held down, its operating system does not boot. Instead, the Mac's firmware enables its drives to behave as a SCSI, FireWire, Thunderbolt, or USB-C external mass ...
NVM Express over Fabrics (NVMe-oF) is the concept of using a transport protocol over a network to connect remote NVMe devices, contrary to regular NVMe where physical NVMe devices are connected to a PCIe bus either directly or over a PCIe switch to a PCIe bus.
Macs made from 1984 to 1998 used Old World ROM as the boot loader for all Macs produced around that time period. From 1998 up until the PowerPC to Intel transition, New World ROM was used for all Macs starting with the first iMac and later expanding to the first iBook and the Blue and White Power Mac G3.
Like Apple_Boot but on Old World Macs, it is used when Mac OS X is installed on a file system not readable by Open Firmware. This partition does not contain a filesystem—instead it contains the BootX machine code in XCOFF format. This partition type was discontinued with Mac OS X 10.3. Apple_MDFW: firmware: firmware
VMware Fusion 3 software for Mac OS X can boot Mac OS X Server virtual machines using UEFI. VMware Workstation prior to version 11 unofficially supports UEFI, but is manually enabled by editing the .vmx file. [147] VMware Workstation version 11 and above supports UEFI, independently of whether the physical host system is UEFI-based.
Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data ...

Many motherboards display a warning message upon boot when a disk drive is approaching failure. Although an industry standard exists among most major hard drive manufacturers, [ 8 ] issues remain due to attributes intentionally left undocumented to the public in order to differentiate models between manufacturers.
