Important Kickstart Differences on AmigaThere are major differences between the early kickstart machines (Kickstart 1.2) and current releases (Kickstart 3.0/3.1)
Size: Kickstart 1.2 was 256Kb. Kickstart 3.0 is 512Kb
Offsets: *EVERYTHING* changes. Do not make any assumptions about any data in rom, for example reset locations, topaz.font data position.
Libraries: Many disk-based libraries under 1.3 are now in ROM, along with disk-validator and other things....
Workbench: Workbench is much improved. Use it.
OS Functions: *Many* new OS functions in all libraries. Now much easier to use, and faster. Much faster than under 1.2/1.3
How to check kickstart
move.l 4.w,a6 move.l LIB_VERSION(a6),d0d0 now contains version number. Compare with the following (all values in decimal)
V0 to V32 - Obsolete! No longer supported. V33 - Kickstart 1.2 V34 - Kickstart 1.3 (1.2 with autoboot for HD) V35 - Early beta-kickstart 1.4. Obsolete V36 - Obsolete! Early V2.00-V2.03 supplied with Amiga 3000 Amiga 3000 owners should upgrade to at least V37 V37 - Kickstart 2.04. Final release version of Kickstart 2 (V38) - Workbench 2.1 (exec.library should not show this version. All true V38 libraries are disk based) V39 - Kickstart 3.0 V40 - Kickstart 3.1 - Currently only in AmigaCD 32Do NOT compare numbers directly, eg.
cmp.w #39,d0 beq kickstart3Always check for greater or equal... eg.
