    UEFI Ram Disk or OS boot loader driver

    Would it be possible for you to add support for installing an OS into a ram disk? I was thinking a UEFI ram disk or OS boot manager ramdisk driver. This would have a decent increase in performance than using primocache 100% l1 cache.

    Thank you.

    But RAM doesn't store data if there is no power. So the RAM disk would need to load up it's entire contents from a hard drive, which would be much slower than just booting from the hard drive in the 1st place.

    (also coding a UEFI driver is very different from a Windows driver, so there would be no quick conversion from the existing Window's RAM drive driver)

      Correct boot up would be a sequential read of the entire virtual disk but performance would be a lot better than any ssd after.

        Probably not much, as commonly used files are going to cached in RAM anyway (or pre-fetched).

        And nothing written to disk would be saved, as the RAM disk is lost when power is lost. So I don't see the practical benefit.
