Bootdisk that's 2090 compatible

[Brian]

Makinga bootdisk that I'd like to be somewhat 2090 compatible, I don't have a setup with a 2090 to test with but I guess HDDisk and Binddrivers are needed but can anyone tell if I also need setpatch and 040.lib?

Yes, HDDisk in SYS:Expansion and the startup-sequence calling Binddrivers are the important pieces. Setpatch is mandatory for 99% of boot scenarios. You'd only need 68040.library if you have a 68040

Sounds like space on the floppy might be an issue? All you really need the disk to do is mount the 2090 and then transfer (re-assign) the system over to the hard drive. You shouldn't have any trouble fitting the above components on a disk for that.

What makes setpatch that important? Why I'm asking is cause I've seen plenty of disks without it that work fine so I wonder if it's mandatory for HDDisk and Binddriver to work? With setpatch having some 040 improvements I guess running it without 040.lib on a 040 system would result in a instant failure... something that doesn't happen atm without setpatch or binddrivers started.

It's part of a normal system bootup. If you're intending to run a "normal" system from the 2090, you should run SetPatch. If you're doing something unusually custom, you might be able to get away without it.

Only real way to find out is to test.

It's only meant to run a program and/or some scripts so definitely not a "normal" system. Wish I had a 2090A to test with on an 040 equipped system but I don't. :/

Wonder under what scenerio anyone with an 040 would actually try to use a 2090A?  Then again, us Amiga users are always trying to do something crazy.

True that but it's more I have 2090A HDDisk and binddrivers command in startup-seq and if I use the same disk on a 040 system even if the 2090 isn't there I don't want it to guru the system.

Why have 2090 support at all? I don't know, call me crazy.
