Thread: KAYPRO and KayFreHD as a hard disk module

  1. #121

    Default

    I'm not the least familiar with the KayPlus ROM, but there are at least two different harddisk layouts (high level formatting) used by Kaypro ROMS, and they are not compatible. I'm not sure I have a detailed scenario where that could cause the symptoms you see, but it may be that the KayPlus ROM does not use the same layout and thus requires that you format when switching ROMs. The Kaypro 10 ROM I used was 81-302, which has a totally incompatible harddisk layout compared to the 81-478 "Universal" ROM. It may not be possible to format the harddisk under the Kaypro ROM and use it on the KayPlus ROM (without reformatting).

    I had errors when I tried to format HD 1. I copied hard4-1 to hard4-0 and then tried again and it could see both drives and allowed me to format and verify both.

    What I'm running into now is when I boot from floppy I can't access the hard drives. If I do a "DIR B:" the FreHD LED flashes but I get a BDOS error. I get a BDOS error and the FreHD LED doesn't flash.

    Any ideas what I might be doing wrong?

    I had the FreHD working just fine with the original 10/83 ROM. If I can't get this working then I'll try the TurboROM but I liked the idea of the RAMdisk in the SWP board working automatically with the Kayplus ROM.
    Alphasite, the thread has on a bunch of different postings stating you need to use the Advent ROm, not the kayplus Rom. The kayplus Rom isnt supported at the present time.

    I asked about it earlier. See jaquinn's response in post #107. With the Kayplus ROM it should be able to see the FreHD and install to it. Since the Kayplus has a much larger set of supported features I thought I'd load it up and see if I could figure out what was causing the issues with running some programs with the Kayplus ROM installed.

    Well then I wish you luck and maybe we can get to the bottom of it for future support.
