Abstract

Dedicated to William Jolitz, 22/7/1957 - 2/3/2022.

The NetBSD operating system was born in 1993 and is based on the 386BSD operating system. Originally it only supported i386 PC hardware, but it has grown into a portable system supporting most consumer computing equipment. During the COVID lockdown, the author took a nostalgic trip down memory lane and made virtual machine images of older NetBSD versions. In a previous paper the author describes the upgrade between NetBSD/i386 1.4.3 and 1.5.4 where the binary object format changed from a.out to ELF. In this paper we tackle all versions between 1.0 to 1.4.3 and then 1.5.4 to present day upgrading using the source code and compiler.
