The reset vector for MIPS32 processors is at virtual address 0xBFC00000, [11] which is located in the last 4 Mbytes of the KSEG1 non-cacheable region of memory. [12] The core enters kernel mode both at reset and when an exception is recognized, hence able to map the virtual address to physical address.
This implies that after the hardware reset, the CPU will start execution at the physical address 0xFFFF0. In IBM PC compatible computers, This address maps to BIOS ROM. The memory word at 0xFFFF0 usually contains a JMP instruction that redirects the CPU to execute the initialization code of BIOS. This JMP instruction is absolutely the first ...
MeepCity was the first game on Roblox to pass 1 billion total visits. [61] The game was averaging 100,000 concurrent players in July 2018. [60] The game received criticism throughout 2021 due to the number of online daters inside the game and inappropriate clothing and actions found in the party feature. This caused the game to be placed as ...

Restoring the software of an electronic device to its original state For the Tilian Pearson album, see Factory Reset (album). A factory reset, also known as hard reset or master reset, is a software restore of an electronic device to its original system state by erasing all data ...
When a system on a chip (SoC) enters suspend to RAM mode, in many cases, the processor is completely off while the RAM is put in self refresh mode. At resume, the boot ROM is executed again and many boot ROMs are able to detect that the SoC was in suspend to RAM and can resume by jumping directly to the kernel which then takes care of powering on again the peripherals which were off and ...
President Joe Biden ordered a national day of mourning in January and flags to be displayed at half-staff following President Jimmy Carter's death.
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 ...
Furthermore, on a modern x86 system, BIOS calls can only be performed in Real mode, or Virtual 8086 mode. v8086 is not an option in Long mode. This means that a modern operating system, which operates in Protected mode (32 bit), or Long mode (64 bit), would need to switch into real mode and back to call the BIOS - a hugely expensive operation.
