I have downloaded this file but am having trouble installing it.

I think the main problem is configuring my wireless network card,and then when i go to choose a mirror to download the rest of the files,it says mirror failed ?

What do the glitches look like? Screenshots?

@jbni

Are you using default theme of OS4? Try a white pattern for WB window background and the stripes might be gone.
This is not removing the problem, but the symptoms - at least here ;)

I finally have Linux installed on the Flex. I have confirmed that none of the Sam Flex graphics issues happen running Debian and KDE on the Flex 667 Mhz with the full 1 Gig of Ram Installed!

It took forever for me to set it up to dual boot AmigaOS4.1 and Debian Lenny. The Sam Flex feels really solid running Linux.

@Jeff

Did you use my tutorial to install Linux? If yes and you have some comments, please tell me.

@Elwood

Yes, I did. I wouldn't have made it without it, Thank You! I needed ALL of the Debian Lenny CDs to get KDE running.

The biggest problem that I had was getting Parthenope to recognize the Amiga partition with the Kickstart files on it. I ended up using SFS/00 and that finally worked. Something is causing a red "Guru" crash about half way through boot up on the Amiga side. The Sam Flex produces a nice display under KDE with the full amount of ram installed.

[Edit]

The "Guru" on the Amiga side was caused be the boot priority on the Linux partition and the Amiga Boot partition both being set to 0. I now have a small KICK: partition that is set as bootable with priority of -127 (Filesystem SFS/00), an AmigaOS4.1 (DH0:) partition set as bootable with a priority of 0 (Filesystem FFS with Long Name Support), and the LNX: (Linux) partition set as bootable with a priority of -17. Everything works perfectly now!


[EDIT] Something seems to have cured the graphics glitches with 1 Gig installed for now. I hope it stays fixed.

Thanks for all the help.

@Jeff

Yes, there's a Guru when the system tries to boot a Linux partition.
You could enter the boot menu (pressing both mouse buttons) to select the volume to boot from.

I updated my tutorial to add the boot priority trick. I have it setup like these since a long time. I forgot to mention it. Thanks.

@Elwood

All of these changes have somehow corrected the graphics glitches on my machine with the full amount of ram installed. I'm not sure if it was putting Kickstart on an SFS partition or what but I am pleased it's fixed.

Thanks again

hmmm, all my partitions are SFS0 for DH0 and SFS2 for all others... could be on to something?

@Slayer

Ok, so I switched all of my Amiga partitions over to SFS/00 and the system is faster and the graphics problems with both memory modules installed are gone. Switch back to a boot partition with FFS and the problems come back. Maybe we are getting somewhere. Thanks for all of the help.

@All

Install the just released Quickfix and see if it fixes the corruption problems.

@Elwood

sadly if would seem that the new update results in graphics corruption on the sam440ep non flex instead

@Elwood
The quickfix appears to have fixed my 800Mz SAM Flex 1GB graphics corruption problems. I don't see the random small black dots in the display now. It's too early to tell what else may be improved.

Great! Cant wait to install it when I get back to the office.

@splurge

My 440ep with the new updates works like a charm. No more green 3d.

@All

Just added the other 512Mb

All looks OK so far! I havent turned on Compositing yet, but I am hopefull all will still be OK.

Edit:

Turned on Compositing, All is still OK Awesome!!!!!

My system is as follows:

SamFlex 800Mhz
1024Mb ram
Radeon 9250 PCI 256MB model
OS4.1 with all the updates installed.

Everything is looking 100% on my system now. No more lines!

It also fixed an issue I had with my mouse. If I left it plugged in during boot it would screw with my resolution, I'd always have to plug it in after I booted up.

@Elwood
I spoke too soon. The graphics corruption on screens and windows may have been fixed by the Hyperion Quickfix but now I have massive graphics corruption on the OS4 splash window if I boot from the preboot screen (The one that opens if you hold down the Help (Scroll Lock) key during a reboot).
