@Kas1e & jabirulo

also to allow booting from usb if needed use

boot1=usb
boot2=ssii

===============================================
Other settings I have :
===============================================
stdout=vga
stdin=usbkbd
menuboot_cmd=boota
boot1=usb
boot2=ssii
boot3=ssii
boota_timeout=2
menuboot_delay=5

First version was a while ago.
Used version 1.11 or so of the driver
Version Sunday used version 2.12 of the driver .
but it should not make a difference .

@TiredOfLife

Interesting.

When I did my Sam460 version I just added the Radeon RX driver to the kicklayout and it boots ok.
I created a USB drive which is writable instead of an ISO or DVD.
Using an Radeon Rx550 4B.
The updated version I did on Sunday gone also works with no other adjustments. Boot USB uses SFS/00 .

@kas1e

Ah ok thank for the clarification.

Heat sink is well glued on on both my fired board and my working replacement (2014 batch). So they may have used a different glue on your batch or it was not properly glued on with your board .
So probably you should Email A-Cube for directions .

@kas1e

For the Sam460ex the script sets

setenv _INSTALL_HWACCEL 0

in all cases.

And unlike the X1000 script there is no


:Installation-Files/GUI-compose.prefs env:sys/GUI.prefs

line so no compositing option set at installation with any video card.

@kas1e

No Composite Support with the RadeonHD Lite version on the Sam460ex ISO .

A 40mm case fan will fit on top of the heat sink.
I replace the original one and it screws on with the screws fitting in the heat sink groves .

@kas1e

If the same heat sink from previous models with groves in them the
Screws to fasten the fan need to fit into the spaces in the heat sink.

@khayoz

Nice.

Additional tip for the X5000/40 :

Replace ehci.usbhcd with the version from the AmigaOS 4.1FE update2 archive or the mouse and keyboard wont work.

@kas1e

Just forwarded you an email.

@AmigaOldskooler

Easiest method is to secure an older model graphics card like a RadeonHD 5450 to setup Uboot and install the OS . As well as a fallback for emergencies .

Same graphics card driver issues exists for X5000.
Emergency boot USB solution with newer video card drivers and Enhancer is supposed to be offered by dealers though.

I don't know if there is an official updated X5000 ISO that supports the X5000/40 but with the original X5000 ISO USB keyboards and mice do not work .
So different issues also exits with the AmigaOS 4.1 FE ISO's .

A1222 on paper looks to eventually have better performance than Sam460 for most things also the A1222 may get multicore support.
But both have to have their production runs to exist for new buyers.
This is the last Sam460 production run and the first A1222 run is to be 200 units. What happens after that is unknown .

The X5000/40 is still available.
But after those in stock are gone that may be it for the X5000 models.

So don't procrastinate too long if you are looking for a new PowerPC motherboard.
Or do like some Amigans and get as many different models as you can .

@AmigaOldskooler

Also as the Sam460 ISO only contains the RadeonHD Lite driver an older video card will be needed to install AmigaOS 4.1 unless the
owner can create a updated ISO or unless Acube bundles a special USB Drive drive that includes the A-Eon Enhancer RadeonRX driver.
This would also require the motherboard UBOOT to be configured in advance to boot from USB by default.

Hopefully things will improve with bug fixes.

As you may recall I tested a bug fixed debug version on Sam460ex.
No crashes with Warp3DNova stuff or video decoding.
So those issues resolved for Sam460ex at least.
Some audio issues but will see if they exist when
I get to test a non debug version .
Still no better performance with 1080p videos though.

Also we now have Kas1e equipped to do some hard beta testing
for X1000 .

@rjd324


Run current AmigaOS 4.1 port of Blender with RadeonRX cards .

@Lozspd4

The RX550 has been my main Sam460ex card since early 2020 .
Also using the same model in the X5000.
The 4k video playback capability and low power consumption are what I prefer. RadeonRX driver and Rx card Video playback Stable on both machines .

The RadeonHD 8570 cards I got just for testing the RadeonHD drivers . I was lucky that they work with the Sam460ex .
But at the price I got them at it was worth taking the chance .

@Lozspd4

Ok thanks.
My Sam460ex pciex1 slot seem to be damaged so have to use onboad sound . No problems with the RadeonRX options.

Also using a sound blaster audigy on the X5000 .

@kas1e

What I understand is that
Onboard Sound is working .
Onboard Ethernet is not .
