    Is it possible to use both cores at the same time?

    Yes, but you have to edit (with some hexedit) the name of the * .A586 ROM if they require other versions.

    I made an a586 -auto and can't enter the menu.
    Can it be avoided somehow?

    Hold down reset while turning on.

    Thanks a lot.


    Was it possible to fix something with PFS?
    FFS often has validation problems.

    I noticed a bug in your CORE.
    Sometimes the FDD doesn't work after the reset (I have gotek from Zaxon).
    He does not see it, the reset does not help, you need to reload the cora.

    Way to go. This 2.0 looks great when it comes to memory.

    When it comes to FAST, in 1.6 it would probably be able to increase, the paths are there. CHIP is another matter, the extra DMA logic in Spartan does not fit.
    Any ideas on how to use 8MB CHIP?

    At the moment I have no plans to share.


    What are the improvements of rev2.0?
