These versions of AmigaOS does not contain the necessary video card driver so booting the CD directly produces no picture. To fix that the SiliconMotion 502 driver has to be added which also needs the latest kernel. This can be done without modifying the CD in a zip file that can then be booted using BBoot as described on this page.

modules from the install CD to a temporary place where it can be modified. You should end up
with a Kickstart
directory containing the contents of

directory with just a Kicklayout
file in it at the root of the CD but that file
has wrong paths so ignore it and only use files and Kicklayout

to add the SM502 driver. Add
a MODULE
line for siliconmotion502.chip
right after where
other chip drivers are loaded after PCIGraphics.card
.
(The PCIGraphics.card
is already there so no change is needed for that
even if it had to be updated to newer version.) The result should look like this:

then you are editing the wrong file, go back to step 1.
above. Some other chip drivers may also be present depending on your AmigaOS version. No need
to change or remove those, just make sure there is a line for the added SM502 driver. Make
sure file names match upper/lower case in Kicklayout
as they are named on disk. In
particular SFSFileSystem is sometimes written as SFSFilesystem which may be a problem as BBoot

when using QEMU v10.0.0 and BBoot v0.8 or newer the same command
works as above with -machine amigaone
, for older QEMU versions that don't support
-kernel
with amigaone
or when using BBoot v0.7 and less use this
command:

installing updates or making any changes to SYS:Kickstart
the same steps need
to be done as above in Step 1 to update the Kickstart.zip
so don't forget to
add the siliconmotion502.chip
driver to Kicklayout
, make zip file
of Kickstart dir and copy the modified zip from the updated machine before rebooting as the
updated system may only boot with the new Kickstart.zip

UDMA mode for IDE devices is
not enabled by default and U-Boot environment variables that can force this were not
emulated yet so this could be enabled by adding a command to startup-sequence
such as:
idetool >NIL: -x a1ide.device 0 69which enables UDMA for IDE device 0 (first hard disk) for more devices similiar line is needed, e.g.
a1ide.device 2
refers to secondary master (usually CDROM
drive). One can check current xfer mode with idetool -u a1ide.device 0
and so on for up to device 3. Missing NVRAM emulation can also cause some applications that
want to access it to crash such as SysMon or C:NVGetVar
so using at least QEMU
v10.0.0 for amigaone
machine is recommended.
With QEMU v10.0.0 and newer NVRAM is emulated and variables enabling UDMA are
added automatically so no extra lines are needed in startup-sequence
any more.
Settings in NVRAM are not saved between runs and reset to defaults on every reboot but if
needed this can be enabled by creating an image with qemu-img create -f raw nvram.bin
4k
and then adding -drive if=mtd,format=raw,file=nvram.bin
to QEMU
command line to keep NVRAM contents in this backing file so settings stored in it will be
preserved between sessions. This is not necessary in most cases as the defaults should work
so this is documented here for reference but you likely won't need this.
