The Primary Bootloader (PBL), which is stored in the Boot ROM [3] is the first stage of the boot process. This code is written by the chipset manufacturer. [4] The PBL verifies the authenticity of the next stage. On Samsung smartphones, the Samsung Secure Boot Key (SSBK) is used by the boot ROM to verify the next stages. [5]
Prior to the development and ubiquitous adoption of the Plug and Play BIOS standard, an add-on device such as a hard disk controller or a network adapter card (NIC) was generally required to include an option ROM in order to be bootable, as the motherboard BIOS did not include any support for the device and so could not incorporate it into the BIOS's boot protocol.
Samsung: Easy (EU and others) Impossible (US) Development settings (except North American cellular variants), however, if modified or custom firmware is flashed, Samsung Knox will be permanently tripped, so Samsung Wallet, Secure Folder and applications made use of the Knox framework will be permanently unusable even if the bootloader is re-locked.
If the sector is read successfully, some BIOSes will also check for the boot sector signature 0x55 0xAA in the last two bytes of the sector (which is 512 bytes long), before accepting a boot sector and considering the device bootable. [b] When a bootable device is found, the BIOS transfers control to the loaded sector.
No drivers are required, but the system functionality is limited until the operating system kernel and drivers are transferred and started. As a result, once the ROM-based booting has completed it is entirely possible to network boot into an operating system that itself does not have the ability to use the network interface.
reboot – reboots the device into either the main operating system, the system recovery partition or back into its boot loader. devices – displays a list of all devices (with the serial number) connected to the host computer. format – formats a specific partition; the file system of the partition must be recognized by the device.
An earlier StrongARM SA-1100 based research handheld device call the "Itsy" had been developed at Digital Equipment Corporation's Western Research Laboratory (later to become the Compaq Western Research Laboratory). The first iPAQ Pocket PC was the H3600 series, released in 2000. [1]
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 ...
