Seeking for a New laptop for work with legacy CSM support option

Hello,

Thank you for your time today.

We know that since 2020, intel and others phased out support of CSM/Legacy. Since then we mostly find computers with UEFI only, 3.0 or 3.0+. For some reasons (we're aware of UEFI advantages, GPT, secure boot etc. - not the question here) we are looking for NEW (not refurbished) laptop for work with CSM/legacy support option. Desktops with legacy still exist, but laptops.. we did not find one, or the info is not available. We assume that maybe a few AMD cpu based laptops may still offer this possibility (legacy bios). Does Acer still offer one product (business line) like this? Thank you very much. Have a great day!

Typically the issue with running a really old OS on new hardware is that current drivers usually don't support the old OS, so you end up with a fair amount of hardware that's not functional. If you are enough of a coder to take generic driver packages from the vendors to recompile for the old OS it's more of a hassle than anything else. If you aren't that skilled in porting drivers you are likely out of luck. Many of the current laptops won't run right even on Windows 10 due to the lack of compatible drivers.

Not that I know of, and I doubt you will be able to find any. Since no currently supported operating systems require the old MBR boot process there is no reason to add that security hole.

Thank you. Actually as you said, it is not for a currently supported OS. But sometimes new hardware is needed with an old OS, real mode…

thank you to all. I know it's quite hard to find. Maybe I've found a prospective way with Coreboot and Seabios, but since I'm not an expert it may be difficult.
