usb boot iso over amidvd on x5k questions

@All
Want to made an emergency usb boot for x5k, but have some strange issue, maybe have a clue ..

What i do now is : take the x5000_install.iso , then, mount it via diskimage gui, and copy whole content to some directory, let's say "new_iso"

Then, i add RadeonRX.chip to the new_iso/System/Kickstart, and add line "MODULE Kickstart/RadeonRX.chip", to the both new_iso/Kickstart/kicklayout, and to the new_iso/System/Kickstart/kicklayout.

Now via rawwrite32 i burn this ISO to usb-stick, put usb-stick inside of x5000, reboot, "Esc", "usb reset" to see this usb stick, and after "Boota".

Then, things start to loads up, i see AmigaOS logo (meaning RadeonRX driver loads fine), then usuall amigaos4 install image (that one which have words "booting" in black color) , and then nothing happens.

I.e. the window asking what to do next (continue to wb futher, install or prepate, etc) do not show up.

The iso i creates is with AmiDVD on my x1000, and i give it a name as in original "AmigaOS 4.1 Final Edition", and also hit "boot AmigaOS4" mark.

On serial also nothing. Just like nothing else executes futher, while should.

If anyone have any idea where to check next, you are welcome. Maybe i just forget something which need to be done with AmiDVD.. Or maybe AmiDVD do or not do something..

Thanks!

I had the same problem when I added RadeonRX but I found a solution -

Open "AmigaOS 4.1 Final Edition:Installation-Support/startprefs.bat"
and comment out the following lines:

;:Installation-Support/CheckHardwareCompose
;if $RC EQ 0
;copy :Installation-Files/GUI-compose.prefs env:sys/GUI.prefs
;setenv _INSTALL_HWACCEL 1
;else
copy :Installation-Files/GUI.prefs env:sys
setenv _INSTALL_HWACCEL 0
;endif


I guess the "CheckHardwareCompose" app gets confused/crash when booting with a RadeonRX card/driver.

@khayoz

Thanks for the hint
that works perfectly

@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.

@khayoz
Oh cool ! It works ! Thanks a bunch :) Probabaly this one need a bit of checking , as seems there some bug or something. I do have serial attached when things stop, but have nothing on serial. So didn't looks like crashes, mostly like some "busy loop" or something

@kas1e

I found for my RX580 that you can force the 'compose' settings and it works correctly. Saves having to change the settings yourself later.

@khayoz

That also worked for the Sam460.

Interesting when i install os4 on my sam (which also have RadeonRX) i didn't have such problem.

Maybes that all related to different radeons ? I mean i use some older RadeonRX version for sam460 when install os4, it was something like 2.3 or 2.4 do not remember. But latest ones are 2.11 for public, so maybe issue starts somewhere after 2.7 or so (there was some heavy code changes in the drivers if i understand that correctly).

In other words, it can be some new bug in radeonrx

I once put an illustrated guide on how I created the stick online. Unfortunately in German, but you can use google translate for the link. However, the menu on the left is then a bit "shifted"

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

I know that of course, but there we load up with RadeonRX driver which we add to the sam460's ISO, RadeonHD is of no use there, and this kind of "stuck" in the startprefs.bat we have exactly with RadeonRX. I didn't tested with RadeonHD, maybe there can be issue also with lite version, but what we all test there is RadeonRX, which do have composite support, and didnt' restricted to anything.

Why then when we use RadeonHD full driver, it loads up fine and pass this compositing check, but when we use full RAdeonRX driver, we didn't pass this check and stuck on.

Sounds like RAdeonRX issue, or i missed the point ? Can you a bit explain your previous post plz ?

@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.

Right... Then i not understand what mean TiredOfLife saying "That also worked for the Sam460.". I readi it like it did the trick for sam460 as well, like before he have the same issue as well.

@kas1e

You understood me well.
I did have an issue before.
Previously The CD wouldn't boot with the RX driver.
Just kept getting stuck at a black screen.
With the amendments as suggested by Khayoz, it now does.

Cheers

@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 .

@Spectre660

That is wierd.
I'd also amended the kicklayout as well originally but no joy.
Using an RX560.

I can't remember if it was version 2.8 or 2.11 of the RX driver.
Kas1e thought he had also done it with a version earlier than 2.8.

I did have 2.11 installed before reverting to 2.8

Think I will do some further tests tomorrow,see if changing between the two without the fix makes any difference.

Cheers

@TiredOfLife


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 .

@McFly

Thanks for this, I was looking for instructions like yours for some time, much appreciated!

Cheers!

@levellord

thank you, I hope it is helpful.
I wish you success

McFly

I've done some further testing.
I can now boot from the CD without the Khayoz fix and with the RX 2.11 driver.

So something else was going in on that prevented the machine from booting.

Maybe time to look at the sata card and cable.

Cheers
