base on Option ROM to boot x86 PCs from NVMe drives (legacy BIOS, INT 13h) # NVMe INT13h Option ROM Boot legacy PCs from NVMe storage: [YouTube video with ThinkPad T43](https://www.youtube.com/watch?v=TVKbFLtXLYM)   This project allows old x86 computers using a classic BIOS to boot from modern NVMe storage attached via PCI(e). It's a heavily modified version of [iPXE](https://ipxe.org/start) (which usually allows for booting from the network), but instead of the network, this code uses a port of the [SeaBIOS](https://github.com/coreboot/seabios/tree/master) [NVMe implementation](https://github.com/coreboot/seabios/blob/master/src/hw/nvme.c) to talk to a local NVMe drive. ## Project status Works™ Very little fault tolerance and testing on different devices. #### Supported hosts - IBM ThinkPad T43 - QEMU VM, i440fx #### Supported SSDs - Samsung SSD 980 - Corsair Force MP510 ## Features - Booting from NVMe storage in Legacy/BIOS mode - Works on 32bit-only CPUs (Pentium 3, Atom, etc.) - Option ROM, USB flash drive, SD card, CD-ROM, chainloading (e.g. from grub) booting supported ## Limitations - Write support is currently disabled. The code is present, but it's additional danger for no benefit (for my usecase) - Only 1 NVMe drive (with 1 namespace) is properly handled at the moment - 64bit BARs are probably not handled correctly (untested!) ## Similar projects / Alternatives There are 2 other Option ROMs publicly available: - Samsung 950 Pro (exposed by the PCIe device, device-specific) - community modded VMWare NVMe ROM (didn't work on my hardware, did work in QEMU) This project is GPL-licensed, can be freely redistributed (both as binaries and source) and can be instrumented/debugged easily (as it's written in C).
