    Hi!

    Thanks! Disabling DMA works.

    Also, I tried booting from a 4.9 CD and floppies (4.9 and 5.2.1-RELEASE)
    and I got the same error. I have disabled everything ACPI related but to
    no avail.

    BTW, if it's not a bother, what does the code below actually do? I don't
    speak asm so I can't tell what are the bad things that my BIOS does :)

    Regards,
    Android66
