There are default settings that are configured in the system BIOS and recognized by the operating system. These default settings can be altered by advanced users. Modern plug and play technology has not only reduced the need for concern for these settings, but has also virtually eliminated manual configuration.
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 ...
The principal duties of the main BIOS during POST include: verify CPU registers; verify the integrity of the BIOS code itself; verify some basic components like DMA, timer, interrupt controller; initialize, size, and verify system main memory; initialize BIOS; pass control to other specialized extension BIOSes (if installed)
As of UEFI 2.7, RISC-V processor bindings have been officially established for 32-, 64- and 128-bit modes. [33] Standard PC BIOS is limited to a 16-bit processor mode and 1 MB of addressable memory space, resulting from the design based on the IBM 5150 that used a 16-bit Intel 8088 processor. [8] [34] In comparison, the processor mode in a UEFI ...
Ralf Brown's Interrupt List (aka RBIL, x86 Interrupt List, MS-DOS Interrupt List or INTER) is a comprehensive list of interrupts, calls, hooks, interfaces, data structures, CMOS settings, memory and port addresses, as well as processor opcodes for x86 machines from the 1981 IBM PC up to 2000 (including many clones), [1] [2] [nb 1] most of it still applying to IBM PC compatibles today.

Settings may be in a different location in each email client, though the AOL server and port settings will always be the same. For additional questions specific to the email client, check the manufacturer’s website. Manufacturers cannot answer questions about your AOL Mail settings, or your AOL username or password.
Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings. It is traditionally called CMOS RAM because it uses a volatile, low-power complementary metal–oxide–semiconductor (CMOS) SRAM (such as the Motorola MC146818 [1] or similar) powered by a small battery when system and standby power is off.
