On v3.8 (Bug exists in r45250 as well). If you have CMD hard drive emulation and CMD Ramlink emulation enabled you can not put the CMD drive into configuration mode. If you load the HD utilites program, put the drive in configuration mode and then try and view, edit anything on that screen it just locks up. If you disable ramlink emulation it works perfectly. This does the exact same thing on both Windows and Mac. Now older version 3.6 in Windows, it works perfect.

    This is actually correct behavior. When you have the RamLink and the CMD HD enabled at the same time, VICE creates a virtual parallel cable between them.

    If you take a look at the RamLink manual (page 2-7), when you have the HD in configuration mode, you have to disable the parallel cable. The HD is in it's ROM bootloader which doesn't speak correctly on the parallel cable, so the RamLink gets confused and locks up.

    You can use @P0 to turn it off, and @P1 to turn it back on (both jiffyDOS commands)
