RamDisk the DoubleEged Sword

[Atheist]

Here's the deal, it took like a week of working this out, but, even then I'm not exactly sure.

Ram: for sure is eliminated on reset or power down, power up. That I realised right away.

Rad: works in 2 ways.
1. On soft re-boot, it survives

2. It can be set up to survive only 1 OR unlimited soft re-boots. This is the part I seem to have come to a conclusion on.

I have it automated in a script file so can't remember how it works, but, if you copy over all of the AOS files to the rad:  do a re-boot, then the OS is completely ram resident. No accesses to the hard drive will occurr.  :-D
Unless you start programs that are still on the HD or the default sub directories are there, in the programs.

You have to change startup-sequence and startupII. It's the assign statements, to "assign c: Rad:c".
I think that's how I did it.

If you want exact info, I'll look it up and post it. Tell me AOS version, model, cpu, and amout of ram.

I believe for it to work, you also have to "Install Rad: boot".

AmigaOne! This it NOT possible on muc, and windrawls rubbish!

Thanks for that info, Billsey

Hello jeffimix,

Yes, warm reset no prob., but if you turn off the Amiga, it is gone.

One more IMPORTANT thing to know is, a RAD: holds a fixed amount of information, and has to be set in the
devs/mounlist
file. in positive ODD numbers. If you set it to 79, that is the EXACT same size as a Floppy disk=880K.

As far as I know, you can't make more than 1 with the original OS. I got a RRD: from a magazine coverdisk a long time ago, that was really cool. It allowed up to 32 RAD: disks, AND they grew and shrank to a maximum preset size.

I love putting games in the RAM: disk, but MOST copy protected games won't work like that. You have to use the RAD: Renaming the RAD: is really tricky too. I had alot of problems with getting that just right (only important when trying to trick games to run in the RAD:)

I used a hex editor on "Defender of the Crown" so that I could play it in the RAD: and, let me tell you, if people SAW that in 1988, they'd of had a heart attack. Everything happenong RIGHT AWAY, section to section of the game. I'm not an expert, I just found a couple of disk references, and replaced them. I didn't break the copy protection on disk one or anything. I could explain that too (not breaking copy protection but DotC, Hack).

BTW, don't anybody get excited, I HAVE THE ORIGINAL.

That's probably when I first found out about the RAD: being erased on a second re-boot. But I believe I saw something about a setting to make it survive multiple re-boots.

Billsey's reference to that other RAD: should definitely be looked at.

I don't think linux could do this either (OS in Ram).

AmigaOne! Back to the GOOD old days!!!
