BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
INT 10h is fairly slow, so many programs bypass this BIOS routine and access the display hardware directly. Setting the video mode, which is done infrequently, can be accomplished by using the BIOS, while drawing graphics on the screen in a game needs to be done quickly, so direct access to video RAM is more appropriate than making a BIOS call ...
However, BIOS manufacturers and OEMs have relied on SMM for newer functionality like Advanced Configuration and Power Interface (ACPI). [9] [10] Some uses of the System Management Mode are: Handle system events like memory or chipset errors; Manage system safety functions, such as shutdown on high CPU temperature; System Management BIOS (SMBIOS)
In the case of a hard reboot, the northbridge will direct a code fetch request to the BIOS located on the system flash memory. For a warm boot, the BIOS will be located in the proper place in RAM and the northbridge will direct the reset vector call to the RAM. In earlier PC systems, before chipsets were standard, the BIOS ROM would be located ...
Encore is a live double-LP by Argent which was released in 8 November 1974, [2] on Epic Records PEG 33079. The performance includes the Rod Argent penned Zombies hit " Time of the Season " (1968) and the Russ Ballard penned "I Don't Believe In Miracles" which was a UK #31 hit for Colin Blunstone in 1972.
Rod Argent put together his eponymous-named band just as his former band The Zombies' post-breakup single "Time of the Season" was becoming a worldwide hit in 1969.His new band employed much heavier rhythms and a generally weightier sound, but also continued the minor keys and complex lyrics of The Zombies, often by Argent's writing with former Zombies bassist Chris White.
Video BIOS is the BIOS of a graphics card in a (usually IBM PC-derived) computer. It initializes the graphics card at the computer's boot time. It also implements INT 10h interrupt and VESA BIOS Extensions (VBE) [ 1 ] [ 2 ] for basic text and videomode output before a specific video driver is loaded.
