Could you please give little more info about that kernel mod ? My understanding is that I will have to add ide.device lib. to my existing ROM image ?... if so , how to do it ? any software is needed ? . Please help :)

Hello,

You need to have a least the ide.device working on $EF0000 to boot. You can just using a floppy disk for booting.
If you want to make it autoboot you need to make a custom rom with ide.device AND bootide.device, you will need to remove scsi.device from the original rom.
I have made a custom rom 3.1 and autoboot work very well on this board ! :)

Thanks for fast replay , but is there any software to manipulate Kernal image ?
PS.
Where can I get a copy of bootide.device file ?

This is not really nice to read this since I'm trying to help you.

You need to extract your ROM content with Remus, remove scsi.device and add both ide.device and bootide.device then create the custom rom.

Here is the source for bootide.device : https://gitlab.com/MHeinrichs/AddBootNode
Its already include in last version on ide.device : https://gitlab.com/MHeinrichs/AIDE/-/blob/master/device/new-version/IDE-DEVICE2.59.zip

@Twisty59
Can you please give me more information about creating the kickstart? I removed scsi.device and added ide.device and bootide.device with Remus. With the patched Kickstart 3.1, CF won't boot and floppy disks won't boot either.

[Twisty59]

Did you have the right ide.device working on $EF0000 ? I maybe still have my custom 3.1 that work perfect with this board. If you have Discord, I can give it to you.

In the meantime I got a patched ROM from someone. Thank you anyway!
