A Startup-Sequence question
« on: September 14, 2005, 03:22:43 AM »
I gave my wife an A3000 w/OS 3.1   .....
She's a gamer  :-D  ..and I have a few CD 32 disks.

The question is .. how can I force the A3k to boot from
the CD Rom if there's a bootable disk in the CD drive.
I tried the inital Boot Options but it doesn't show the
CD Rom as a bootable drive (the CD drive is installed
and working properly).
Can I add something to the Startup-Sequence ??

 Well, one thing is for sure..you will NOT be able to run most CD32 games on an A3000, as its not AGA compatible........some CD32 games are not AGA, so they might work.

Make your CDROM master and the HD slave......that might work.........but maybe just the CDTV games.

CD32 is actually the best Amiga ever made by Commodore!...

Most of these games are Shareware and PD.
They are old disks and I doubt that very many of
the games are AGA only.
The CD's are also CDTV compatable.

This is an A3000 SCSI  Not IDE

Your CDROM drive is attached externally, right?

Hi,

The A3000 doesn't have any CD filing systems in its Kickstart ROM, so unfortunately, it's not possible to boot directly from the CD.

However, you could probably bodge something together using the hard drive's startup-sequence so that the main device/drive assignments were directed at the CD drive, after an applicable filing system had been loaded.

You might be better off looking at something like WHDLoad, and just install a load of games to the hard drive...

I was thinking of something along this line ...

I tried adding a line at the beginning of the
startup-sequence in Dos.  The line .......
"If Exists CD0:S/startup-sequence"
But it doesn't see the CD Rom yet at the beginning
of the startup sequence, so if I can mount the CD Rom
then make the switch to the CD Rom startup-sequence it
might work.
Any ideas ??

You'll need to mount CD0: before you try to use it.  If CD0 is in Devs:DOSDrivers, you'll need to move the portion of the Startup-Sequence that mounts those before your "IF EXISTS CD0:...", or you could call "mount" for CD0:.  Of course, you'll also need the CDFileSystem in L:.

Though I doubt you'll actually get a CD32 game to run on an A3000 anyway.

Most of these games are not AGA. I've run a few of them
by just copying them into ram and running them from there.
If I can force the A3k to boot from the CD then I can use
the menu on the CD to run the games (I think  :idea:  :-) )

I'm going to try moving the 'If Exists' statment down in
the startup-sequence to after all the drives are mounted
but I'm unsure how this effect the startup...
Its worth trying  :-D

I use an old commercial program called CDBoot. What it does is add a few lines to your startup-sequence to mount CD0 and then boot from CD0:s/startup-sequence. It also tries to emulate a CD32 as best as possible by disabling Fast RAM, CPU caches, etc.

If you can find a copy, it'll do exactly what you need it to. If you can't find it, there *might* be a similar shareware program on Aminet; I can't quite remember though.

A possible manual alternative:
Get to the Emergency Startup Control menu. Disable CPU caches. Boot without a startup-sequence
1> Assign ENV: RAM:
1> Mount CD0: from DEVS:DOSDrivers/CD0
1> Execute CD0:s/startup-sequence

You might also need to manually reassign libs:, c:, l:, etc to the CD. You might be able to make a simple boot floppy that does all this, too.

Startup-sequence if I may add - is very generic.
