IDE autoboot for TOS 1.04

[czietz]

In contrast to EmuTOS or TOS 2.06, TOS 1.0x cannot boot from IDE. Fans of TOS 1.04 (e.g., because of certain games) with an IDE interface such as the Lightning ST consequently always had to load the harddisk driver from floppy or an ACSI disk.

Since it was a wish of our Lightning ST customers, I wrote a patch for TOS 1.04 that allows this TOS version to boot from an IDE drive, too. For example an IDE/SD adapter, a CF card or an IDE Disk-on-Module. It was successfully tested with HDDRIVER and AHDI.

Since for obvious legal reasons I cannot distribute a patched TOS, I made the changes so they can be applied with the TOSPatch program.

Files (incl. source code) and a short description are available at https://github.com/czietz/ideboot/ and the current snapshot can be downloaded as https://github.com/czietz/ideboot/archive/master.zip.

Enjoy! (But please note that Spanish and French TOS are unfortunately not supported, because the translation takes too much space in the ROMs.)

Nice,even if I prefer to boot my IDE from floppy on my 'gaming' machine.

Very useful hack!

[czietz]

Obviously, I personally still prefer to run EmuTOS (256k ROM) on my ST, but I know that there are people using games or software that only runs with Atari TOS 1.0x.

Sweet!
I am planning on upgrading my Mega ST with a MonSTer for TOS switching and internal IDE mass storage. Your patch is PERFECT for my project!

Thank you!

The last few bytes in the ROMs are from the DESKTOP.INF. If you are sure that such a file already exists on the harddisk, you could theoretically overwrite part of it.

Here is a MonSTer (alanh) that I purchased from Darklord and installed in my Mega ST4.

The Mega ST4 was from the UK, so I replaced the PSU with a meanwell. I used the IDE auto boot 1.04US TOS from Czietz. I added with an ide2sd adapter and I added a gotek because the mechanical floppy drive was failing.

Works great!
Thanks again!

Thanks for this patch, works perfectly! It's running in my Mega ST4 with homemade IDE board. This Mega ST4 is now becoming a bit more awesome .

Here you have TOS in Spanish, patched to autoboot from IDE.

Versions: 1.04, 1.06 and 2.06

All from ppera sources.

Greets.

I'm afraid this does not work with HDDRIVER, whereas my patch does. Afaik, ppera's patches require his harddisk driver. BTW: TOS 2.06 autoboots from IDE just fine; it does not need any patches.

[crashman]

well, at last the spaniards had something to autoboot from...

[ThorstenOtto]

All from ppera sources.

From ppera? You mean the ones which he stole from my work, claiming he did it himself?

[crashman]

Well, I don't know that.

From ThorstenOtto work.

By default, the IDE disk is located at $F00000. How to make TOS (GEMDOS) look for an IDE disk at a different address (reading track 0)? Before I even install the driver.

$00046A long (Vector for hard disk initialization) - hdv_init ?

Because you're posting in this thread, I'm assuming that you're talking about my patch for TOS 1.04. In that case, just change the address in my patch...

... and rebuild.

I didn't want to create a new topic
Thank you for the information. And how to do such a thing under 2.06 / 3.06?
So that TOS would look for IDE disk elsewhere. Even before any driver enters the action.
Is it enough to change this address in ROM?
