Install them into your Amiga as you would a normal Amiga ROM and you are finished!.Load each image into the Willen programming software, perform a Byte Swap operation on the buffer, and then write each image to the EPROM chips.Concatenate U6A_temp.bin to itself to create U6A.bin, with a filesize of 512K and do the same for U6B.Which creates the two files U6A_tmp.bin and U6B_tmp.bin Dissect the file Wordwise, and create 2x256kb files (so it is split to fit onto the two physical Kickstart EPROMs.

Next copy the ROM image to a Windows based PC and load the image into WinHex.

Next test the image by using BlizKick (or another method of softkicking a ROM image on a real Amiga).

Build these files back into a ROM image, by combined the files using the Remus utility.

While your EPROMs might be larger, the Amiga expects to find a 512KB ROM image, so your final total ROM size must remain that size. Note: When doing this make sure you keep an eye on the complete ROM size.

As mentioned above, you could remove vice from the rom if you don't use the on-board IDE interface, and replace it with a different file such as vice.

Remove any files that you won't need, and add any additional ones that you require.

Replacing any older versions from the 3.1 ROM files with the newer ones contained in the 3.9 Update.

Combine the 3.1 ROM's files with the ones in the newer AmigaOS 3.9 ROM Update.

Use Doobrey's RomSplit utility to split the AmigaOS 3.9 AmigaOS Rom Update files into it's component parts (files).

Use Doobrey's RomSplit utility to split the resulting image file into it's component parts (the files contained within it).

Read the contents of your 3.1 ROM chip into an image file.

The process to make a Kickstart 3.9 ROM set is as follows:

Doobrey's RomSplit and Remus utilities - see Downloads.

A Willem EPROM programmer and Windows PC to control it.

For example you could remove the original vice from the ROM image if you don't use the Amiga's original on-board IDE interface, and instead add a different device driver needed for the HD hardware you actually use, such as vice.

Therefore allowing the Amiga to boot into AmigaOS 3.9 without first needed to patch the system and perform a soft reboot.Īnd while creating this custom ROM image you can take the opportunity to customised the files it contains for your own needs. And a new ROM is then built which contains both. The custom 3.9 ROM is built by combining the files from the original Kickstart 3.1 ROM version, with the files from the AmigaOS 3.9 ROM update. By combining the files from the original Kickstart 3.1 ROM with those included in the AmigaOS 3.9's ROM Updates and making a new updated ROM it removes the Amiga's need to first need to run the setpatch to add the newer files into the system. This is where this custom Kickstart 3.9 ROM comes in. Logically, had Commodore still existed they probably would have released an updated kickstart ROM that contained the updates this Patch adds, instead of needed to patch the system in memory every time it boots. Kickstart 3.9 is instead is a custom "scene/homebrew" ROM created by the Amiga community for use with AmigaOS3.9.Īlthough AmigaOS 3.9 boots fine using a Kickstart 3.1 ROM, before AmigaOS 3.9 actually loads it normally first needs to patch the system by running setpatch to add the additional AmigaOS ROM Updates required for 3.9, and then once they are loaded/patched the system reboots and then loads AmigaOS 3.9. When you get to the last file wbfind you will notice that it is not there - it can be found in ROM/wbfind as part of the WT31.lzx archive.There wasn't an official Kickstart 3.9 ROM released by Commodore, or any other Amiga company. Then proceed to the next file from the list above that must be added and so on, till you add all the files. Note the version and then compare it to the exec.library in the BoingBag 2 update ( 44.57_ROMUpdate(3.9bb2)) and add the one with the highest version. First check the Kickstart 3.1 directory ( 40.68(A1200)) for exec.library. In order to add files, follow this easy procedure: we need to add exec.library. The order in which the files should be added is the following - all these files are required: If you look in the 40.68(A1200) directory and the 44.57_ROMUpdate(3.9bb2) directory, you will notice that the version numbers are conveniently added to the file-name which will help you add the newest version.
