PRODUCT DESCRIPTION
The BIOS platform software was developed by Teleplatformy LLC based on Coreboot - a project to create free software for initial hardware initialization and launch of modern 32-bit and 64-bit operating systems.
"Coreboot" replaces the original (proprietary and closed) BIOS of the motherboard without losing basic functionality and ensures the full functioning of hardware components and peripherals. The results of the Coreboot project are distributed under the terms of the GNU GPL v2. - https://github.com/coreboot/coreboot.
The BIOS software is based on the source codes related to the "Harcuvar" platform of the "Intel" company (the base platform for Intel Atom processors of the C3000 Denverton family).
"SeaBios" is used as the bootloader of the operating system.
The platform uses SPI Flash Memory W25Q128FV (WinBond Electronics Corp) with a size of 16 Megabytes as a storage chip for the BIOS ROM file.
For the initial loading of the BIOS ROM file into the platform flash memory chip, it is recommended to use standard SPI Flash programmers (for example, SF100 - https://www.dediprog.com).
