SeaBIOS is an open source implementation of a 16-bit x86 BIOS, serving as a freely available firmware for x86 systems. Aiming for compatibility, it supports standard BIOS features and calling interfaces that are implemented by a typical proprietary x86 BIOS. SeaBIOS can either run on bare hardware as a coreboot payload, or can be used directly in emulators such as QEMU and Bochs. Initially, SeaBIOS was based on the open source BIOS implementation included with the Bochs emulator. The project was created with intentions to allow native usage on x86 hardware, and to be based on an improved and more easily extendable internal source code implementation. == Features == Features supported by SeaBIOS include the following: * Graphical bootsplash screen (JPEG and BMP) * USB keyboard and mouse support * USB drive booting support * Boot from USB Attached SCSI * Support for 32-bit PCI BIOS calls * ATA DMA and bus mastering support * Support Universal Host Controller Interface (UHCI), Open Host Controller Interface (OHCI), Enhanced Host Controller Interface (EHCI), and Extensible Host Controller Interface (xHCI) * Support systems with multiple VGA cards * Boot menu that allow booting from any drive or any CD-ROM (El Torito) * BIOS Boot Specification (BBS) calls * Rebooting on Control-Alt-Delete key press * Dynamic e820 map generation * Logical block addressing (LBA) 48-bit * POST Memory Manager (PMM) * Paravirtualization, Xen HVM, Virtio * Payloads (LZMA compressed) * VESA BIOS Extensions (VBE) 3.0 * PCI Firmware Specification v3.0 * SeaBIOS as a Compatibility Support Module (CSM) for Unified Extensible Firmware Interface (UEFI) and Open Virtual Machine Firmware (OVMF) * Virtual machine host notification of paravirtualized guests which panic via the pvpanic driver * A patch exists to load the SLIC table from a licensed OEM Windows BIOS.〔(【引用サイトリンク】title=ghuntley/seaslic GitHub )〕 SeaBIOS has support for APM 1.2, Enhanced Disk Drive (EDD) 3.0 (INT 13H extensions), SMBIOS 2.4, MultiProcessor Specification, BIOS Boot Specification (BBS) and ACPI. It does not support ESCD. SeaBIOS's boot device selection menu can be accessed by pressing during the boot process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SeaBIOS」の詳細全文を読む スポンサード リンク
