Although that makes sense, why the bootblock works when running with the runbootblock utility from AmigaOS 3.2? The Recoverable Alert will only happen when trying to boot NetBSD from the Early Startup Menu. Is there something different in the memory layout before actually booting AmigaOS? Regards, Carlos PD: Just to remember, I didn't try bootblock in rom 3.1.4 since I don't own it; maybe the breaking changes (whatever it is on the NetBSD o kickstart code side) began there and they were just carried to 3.2. As I said, bootblock is working fine in 3.1. Carlos Milán Figueredo | HispaMSX System Operator | http://www.hispamsx.org | telnet://bbs.hispamsx.org | https://calnus.com
