Okay, I'm seriously considering adding a ROM switch to my A2000 due to incompatibility issues in several programs.
My question is, IF I wanted to hd boot either 2.x or 1.x, how would I do that?
I see how the ROM switch works, but would I be able to select which OS version booted from the hard drive? Would I need a second hard disk?
Or is this even possible without using a removable drive of some sort?

insert at the beginning of your s:startup-sequence (assuming you've got 3.1 installed to the "wb3.1" folder, but it can be anywhere):
if "$Kickstart" eq "40.69" ; change to appropriate version to check
assign SYS: SYS:wb3.1
CD SYS:
assign FONTS: fonts
assign L: l
assign LIBS: libs
assign DEVS: devs
assign C: c
assign S: s
assign T: ram:
execute s:startup-sequence
quit
endif
Been using 2.x & 3.x that way for ages on the same partition, IIRC even 1.3.
-
Don't have 3.1.
I'm working with legacy systems, 2.x and 1.3.
-
You could configure your system so that if nothing done it boots straight into 1.3 and if 2.x kick is chosen you could boot into it via early startup screen - that's what I've had.

i had a same problem and used the startup like in OS4, here it is:
----
Assign t: RAM:
Version exec.library VERSION 38 >NIL:
If WARN
assign SYS: dh0:AmigaOS/wb2.1/
CD SYS:
assign FONTS: fonts
assign L: l
assign LIBS: libs
assign DEVS: devs
assign C: c
assign S: s
Else
assign SYS: dh0:AmigaOS/wb3.1/
CD SYS:
assign FONTS: fonts
assign L: l
assign LIBS: libs
assign DEVS: devs
assign C: c
assign S: s
EndIf
execute s:startup-sequence
quit
----
my root on dh0 partition contains only few directories (amigaos, c, s) and used commands are from wb2.1; for some reason, Zacs solution didnt work directly.
