A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program.

Generally, the major number identifies the device driver and the minor number identifies a particular device (possibly out of many) that the driver controls: [6] in this case, the system may pass the minor number to a driver. However, in the presence of dynamic number allocation, this may not be the case (e.g. on FreeBSD 5 and up).
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 ...
By convention a receiving device sends an ACK to indicate it successfully received a message. ASCII also provides a NAK code point (0x15, binary 0001 0101) which can be used to indicate the receiving device cannot, or will not, comply with the message. [2] Unicode provides visible symbols for these ASCII characters, U+2406 (␆) and U+2415 (␕).
Blue screen errors have existed since the first beta release of Windows 1.0; if Windows found a newer DOS version than it expected, the boot screen would have the text "Incorrect DOS version" alongside other messages detailing what check failed to pass appended into it before starting normally. [4]
On many Allwinner systems on a chip (A10, A20, A64), the boot ROM either waits for a bootloader to be loaded through USB (if a specific PIN is high) or tries to boot on several peripherals in a fixed order. [5] Some Allwinner systems on a chip can verify the signature of the booloaders. [6] But most devices being manufactured are not configured ...
Even though string literals should not be modified (this has undefined behavior in the C standard), in C they are of static char [] type, [11] [12] [13] so there is no implicit conversion in the original code (which points a char * at that array), while in C++ they are of static const char [] type, and thus there is an implicit conversion, so ...
