Other core components from the PC/XT/AT eras *could* be next. Maybe I get it wrong and the current CSM is implemented as a payload that works on its own.Įdit: Seems removal of CSM may only be the beginning. Please forgive my ignorance, but I know very little about UEFI's internals. But if UEFI uses an standardized API/ABI,Ĭouldn't a generic version of SeaBIOS run atop of UEFI and provide some degree of backwards compatibility ? Unfortunately, I don't know what to make of that. Unified Extensible Firmware Interface (UEFI) and Open Virtual Machine Firmware (OVMF)". The Wikipedia article of SeaBIOS mentions " SeaBIOS as a Compatibility Support Module (CSM) for In the future, could good old SeaBIOS be used as an alternative CSM, perhaps ?
I am more like guessing that the problem will basically be newer system won't support corresponding bus (ISA, PCI, PCI-X etc.) Reply 7 of 14, by Azarien Booting from it would, but from my experience, those devices are used mostly as data storage. Connecting an old disc array to a newer computer isn't an issue. Maybe using tools from this century would help? ? Hiren's Boot CD - yes, it's not updated since a long time. I bet all major Linux distributions support UEFI boot. Secure Boot requires CSM to be disabled.
Most HDD tests I've seen are Windows only. Flash tools for EFI shell / Windows / Linux exist for many, many years already. will they work in a non-legacy UEFI environment? Those systems use HBAs with their own BIOS. What about older/legacy cards with BIOS? Think about a business that (for some reason) needs to connect an old (SCSI of FC) disk array to a newer computer. Hiren's Boot CD (not updated since a long time, but still useful) and Ultimate Boot CD. I'm thinking about secure booting and (although the link does not say anything about it) maybe they'll force it. Some flavours of Linux don't fully support UEFI. There are some bootable tools (are Memtest and Memtest + still developed?) that doesn't fully support UEFI, or does not support it at all. DOS is still useful for some things, like HDD tests and BIOS flashing on some devices. I'm worried about alternate OSs and legacy hardware.
