Hello,

I've bought an old Mac IIsi with 850 MB SCSI hard disk, 17 (!) MB or =
RAM, a video card with 19" display and an Asante EN/SC SCSI Ethernet =
adapter.=20
I'm quite sure that there is only the standard System 7.1 ("D1-7.1") =
with the appropriate network drivers on it.

I tried to boot the netbsd kernel with NetBSD/Mac68k Booter and got the =
following:

This seems normal to me. But then the kernel writes:

You're hosed! Try booting with 32-bit addressing enabled in the memory =
control panel.
Older Machines may need Mode32 to get that option.
panic: Cannont work with the current memory mappings.

Stopped at  _Debugger+0x6:   unlk    a6

32-bit addressing IS enabled (the Booter says that it runs only with =
32-bit adressing when I disable it), virtual memory is disabled, volume =
cache has 1024K.
I noticed that the version number of the memory control panel was 7.3 =
but I restored 7.1 to match the system, but this didn't work, too.

Has anyone an idea on how I could fix this?
