Microsoft reserves a chunk of disk space using this MSR partition type, to provide an alternative data storage space for such software components which previously may have used hidden sectors on MBR formatted disks. Small, special-purpose partitions can be allocated from a portion of the space reserved in the MSR partition. [1]
A WDTLER.EXE utility allows the enabling or disabling of the TLER parameter on Western Digital hard drives. This utility is written for DOS. The utility works on and makes changes to all compatible Western Digital hard disk drives connected to the computer. The change survives power-cycling. Western Digital used to mention the tool in an FAQ. [12]
In CP/M, attempting to read a floppy disk drive with the door open would hang until a disk was inserted and the disk drive door was closed (very early disk hardware did not send any kind of signal until a disk was spinning, and a timeout to detect the lack of signal required too much code on these tiny systems). Many users of CP/M became ...
The boot partition (or boot volume) [5] is the disk partition that contains the operating system folder, known as the system root or %systemroot% in Windows NT. [6]: 174 Before Windows 7, the system and boot partitions were, by default, the same and were given the "C:" drive letter.
initialize, size, and verify system main memory; initialize BIOS; pass control to other specialized extension BIOSes (if installed) identify, organize, and select which devices are available for booting; The functions above are served by the POST in all BIOS versions back to the very first. In later BIOS versions, POST will also: initialize chipset
INT 13h is shorthand for BIOS interrupt call 13 hex, the 20th interrupt vector in an x86-based (IBM PC-descended) computer system.The BIOS typically sets up a real mode interrupt handler at this vector that provides sector-based hard disk and floppy disk read and write services using cylinder-head-sector (CHS) addressing.
This applies only to removable disk drives. Some boot loaders make adjustments or refuse to pass control to a boot sector depending on certain values detected here (e.g., NEWLDR offset 0x018). The boot ROM of the Wang Professional Computer will only treat a disk as bootable if the first four characters of the OEM label are "Wang".
Click of death is a term that had become common in the late 1990s referring to the clicking sound in disk storage systems that signals a disk drive has failed, often catastrophically. [1] The clicking sound itself arises from the unexpected movement of the disk's read/write actuator. At startup, and during use, the disk head must move correctly ...
