In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module. Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
USB 3.0 SuperSpeed – host controller (xHCI) hardware support, no software overhead for out-of-order commands; USB 2.0 High-speed – enables command queuing in USB 2.0 drives; Streams were added to the USB 3.0 SuperSpeed protocol for supporting UAS out-of-order completions USB 3.0 host controller (xHCI) provides hardware support for streams
Example of a 4GB USB flash drive. For the purposes of this list, a portable application is software that can be used from portable storage devices such as USB flash drives, digital audio players, PDAs [1] or external hard drives. To be considered for inclusion, an application must be executable on multiple computers from removable storage ...
The command supports physical and virtual storage including hard disk drive (HDD), solid state devices (), and solid state hybrid drives (). [5] It provides control over the testing methods, duration, threads, queues, IO and processor affinity, and reporting.
The Linux kernel has supported USB mass-storage devices since version 2.3.47 [3] (2001, backported to kernel 2.2.18 [4]).This support includes quirks and silicon/firmware bug workarounds as well as additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA-USB bridges, used for S.M.A.R.T. or temperature monitoring, controlling the ...
A design flaw causes devices connected to the Lynx Point's integrated USB 3.0 controller to be disconnected when the system wakes up from the S3 state (Suspend to RAM), forcing the USB devices to be reconnected although no data is lost. [28] [29] This issue is corrected in C2 stepping level of the Lynx Point chipset. [30]
Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
However, programs like Mac Linux USB Loader can alleviate the difficulties of the task of booting a Linux-live USB on a Mac. This limitation could be fixed by either changing the Apple firmware to include a USB driver in BIOS mode, or changing the operating systems to remove the dependency on the BIOS.
