Can't install MorphOS on Sam460LE

[skygecko]

Hi, any Sam460 users here? Tried to install MorphOS on my new Sam460LE board, but it won't boot. Either the SD Card image nor the Live CD will boot, I only get a blank screen. AmigaOS 4.1 just boots fine via SD or CD, so why does the system refuse to boot MorphOS?
Any ideas what the problem is?

Is it even supposed to work with Sam460LE? From their web pages it looks only CR and EX are supported.

The specs are nearly identical to the CR model, so why should't it work as well?
But I could imagine the installer sees the LE as an unsupported model and refuses to run...
If that's the case, I probably have to wait for Morphos 3.18.

It works on my Sam 460LE.

It may be your graphics card..

Make sure it's compatible with MorphOS!

I have a ATI Radeon X1950 XT, which is supported by MorphOS!
And my SiI3112 SATA card as well.
I even used dd tool to copy the hdimg to the SD card.
So it must be something else...

make sure to follow morphOS instructions.. from the morphOS page

ACube Sam460

The Sam460 supports installation both via CDROM and via SD card inserted into the internal SD card slot of the Sam460. We recommend installing from CD where possible.

via CD

    Turn on your Sam460.
    When prompted to do so by the firmware, press enter on the keyboard to activate the boot selection menu.
    When the boot selection menu appears, press enter again to activate the boot device menu. From this menu either choose '3x12 SATA DVD' or '3114 SATA DVD' depending on which SATA controller your optical drive is connected to. If you are not sure, then try first the one and then the other.
    Press enter to confirm your choice in the boot device menu, then escape and enter again to select 'boot this configuration'.
    MorphOS will now start booting. Once it is done booting, follow the on-screen instructions.

via SD card

    Download morphos-3.17-hybrid.hdimg.
    Write morphos-3.17-hybrid.hdimg to an SD card directly as a disk image.
    Insert the SD card into your Sam460's internal SD card slot.
    Turn on your Sam460.
    When prompted to do so by the firmware, press enter on the keyboard to activate the boot selection menu.
    When the boot selection menu appears, press enter again to activate the boot device menu. From this menu choose 'USB HD'.
    Press enter to confirm your choice in the boot device menu, then escape and enter again to select 'boot this configuration'.
    MorphOS will now start booting. Once it is done booting, follow the on-screen instructions.

I am well aware of these instructions from the MorphOS page 

The problem still is: by performing these steps, either with CD or with SD card, I only get a blank screen, so I can't "follow the on-screen instructions".

[SACC-guy]

Well then..

It goes back to (since mine works and I use a Radeon 4650)

I still think its the Maybe the video cable? (try dvi cable)

[skygecko]

The card only has 2xDVI (tried both) and S-Video connectors. The X1950 XT is listed as compatible on the MorphOS page, so I don't think it's a GPU issue (but you can still try to convince me of the opposite    )

What I received from the serial terminal doesn't give me a clue either:

MorphOS boot loader version 1.10
Booting from HDIMG0
Trying to load "bootsam_ppc4x0.img" from "HDIMG0:"...
Loaded "bootsam_ppc4x0.img" from "HDIMG0:", booting...

So it really looks as if the installer either stops right after "booting..." or it just isn't diplaying via my GPU. But then: WHY?

Any more ideas greatly appreciated
