    Development can begin from existing resources like a kernel, an operating system, or a bootloader, or it can also be made completely from scratch. The development platform could be a bare hardware machine , which is the nature of an operating system, but it could also be developed and tested on a virtual machine.

    In x86 computers, a first-stage bootloader is a compact 512-byte program that resides in the master boot record (MBR) and executes when a computer starts. Running in 16-bit real mode at address 0x7C00, it performs minimal hardware initialization, sets up a basic execution environment, and locates the second-stage bootloader.

    The first stage bootloader, which is a part of the MBR, is a 512-byte image containing the vendor-specific program code and a partition table. [6] As mentioned earlier in the introduction part, the first stage bootloader will find and load the second stage bootloader. [6] It does this by searching in the partition table for an active partition. [6]

    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 ...

    BYOOS has been made possible thanks to the ability to create USB pen drives and other external storage devices with 'live' operating system images containing all the necessary drivers to allow boot up and operation on any compatible computer. Bootable versions of Linux were available by 1993.
