Amiga 500 - KS 1.3 boot from internal IDE

[giobbi]

Hi all!

IN SHORT: I NEED THAT SOME GOOD HEART SEND ME THE PATCHED KICKSTART 1.3 WITH THE HARD DISK BOOT PATCH....  (more info below)

I've successfully built and installed an internal IDE hard disk in my A500. BTW For anybody who wish to do the same, I'm leaving here three links about what I've found on the web and I used to build mine:

https://www.mklboards.fi/ide/a500ide.html (original project, I believe...?)
https://modelrail.otenko.com/c64amiga/amiga-500-internal-ide-port (a very good and useful tutorial, read it!)
https://www.pcbway.com/project/shareproject/Amiga_500_IDE_Emulator.html (the PCBway page, for lazy boys LOL)

NOTE: I used a 4 Gb D.O.M. (disk on module) that fits perfectly above the KS ROM. I also connected a +5V to the pin #20 of the HDD connector, so the DOM gets the power directly from the PCB and there's no need to add wires and solders on the Amiga main board.

I also transferred the WB 1.3 onto the HDD and made a minimal floppy boot (it begins booting by FDD and then load the WB from the HDD).

But the final cut would be a full boot from HDD, without FDD.

There are some instructions about how to patch it. I followed the instructions, and I got a KS 1.3 patched, but it has some errors and when I slap it into an EPROM, it doesn't work on my A500.
I tried many times, followed many instructions, apparently I did everything right (but of course there's something wrong there).

I have an Amiga 500, so I'm supposed to be authorized to own a KS 1.3.

Anybody that owns the patched KS 1.3 that boot directly from HDD would be so kind to share it with me?

Thanks in advance!

I know... but if you have the file, can you kindly send it to my email address, atacama1968 at gmail, of course dotcom?

[giobbi]

Even sending it by email, is same thing.

I understand, but I do have an Amiga 500 with the Kickstart 1.3, so this wouldn't be a copyright violation, don't you agree? If I hadn't, why I was trying to find a modded KS 1.3 ?

If I recall, there was a patch. I remember downloading it an using it to inject 3.1 scsi.device into 1.3 rom.

Can't remember where I got patch from. As it was around 15 years ago.

EDIT:- You could just use Remus and romsplit.
Pull apart KS1.3 and KS3.1 and build a 512kb ROM with all modules from 1.3 and add scsi.device.

I tried to do patch it but I went wrong somewhere, so I got an invalid KS that simply doesn't work on my A500.

I tried this one:

https://www.fpgaarcade.com/kb/how-to-boot-from-a-hdf-on-the-amiga-500-under-kickstart-1-3-on-the-replay/

That is the only tutorial I found... but for some reasons It didn't work for me.

it refers to the https://aminet.net/package/util/boot/kick13scsipatch patch.

This one: https://github.com/KimJorgensen/Amiga-IDE-Boot-Rom  seems promising but it comes with poor instructions (maybe enough for anybody who already knows what he's talking about... not enough for me, unfortunately).


I'm trying to understand what Remus is and how it would help me. Sorry, I'm quite a newbie about Amiga and I don't know much of it; for that reason I was trying to find someone that would send me a modded KS .bin file

Hi. Amiga scsi.device won't work with the two chip ide interface, it uses "ide.device"
I don't know if ide.device is compatible to put in to ks-rom.
IDE68K on the other hand is supposed to be clone of A600 ide, but it is not certain if scsi.device will work when combined to KS1.3. I haven't tried it myself.
In this video it was tried and I think there was some problems https://youtu.be/RwpNdzTakyI

Oh, you are THAT youtuber! :-) Great video, I watched it before to open this thread (and also discovered and tried that patch you found). However my modded KS is totally unusable; the Amiga doesn't boot (black screen). Just to be sure, I downloaded the content of my original 1.3 KS using my TL866A and the 27C400 adapter, and then I used the image to write a 27C400... that works perfectly on my A500. Just to be sure I hadn't a different problem.

Would you mind to kindly send me your  working .bin file by email, please? It would totally solve my problem, I suppose...

BTW: I attached a picture just to prove I really own an Amiga with an internal IDE hard disk

I decided to try again, following carefully the youtube tutorial. It seems I got exactly what he's showing in the video, but now I'm stuck for a silly problem:

He's showing the ByteSwap program, but I can't find it on the web and I don't know what is it for.

Anybody has this program? Is it free, can you kindly attach it here, or give me a link to download?

I finally get some results, at least I got a booting (I mean: it doesn't hang during the bootstrap), patched kickstart. But nothing is easy, so it doesn't boot neither from HDD, nor from FDD.

I'm trying to understand if the problem is becuase my hard drive (FAT32) isn't bootable...  It works fine with the stock Kickstart and the "minimal boot" floppy (the workbench is on the HDD but it uses a FDD to begin the boot).  But it doesn't boot using the modeed kickstart.

Maybe it doesn't like the FAT32 based HDD ? Or some files are missing?
