Re: Data Access Exception when trying to Boot installed NetBSD of hard drive

[Adrian Christiansen <adrian.christiansen%gmail.com@localhost>]

Hi Georg!

I don't know if I should be happy or sad, but this actually got the
system to boot. I used boot from 3.1 and the bootxx from 6.1.5. So
there's my problem, I need a new BootROM I guess... or boot should be
fixed?

Thanks!,
Adrian.
