Amiga Events : Radeon HD Cards Now Work with the SAM 440ep Motherboard

Posted by Mikey_C on 2009/12/7 21:24:36 (2938 reads) News by the same author

From Hans de Ruiter's website (2009-11-27):

This morning ACube Systems released UBoot updates for their SAM 440ep and SAM 440-flex motherboards. These updates include fixes that allow Radeon X1000 series and higher (e.g., Radeon HD 2400) cards to work with the SAM 440ep. Previously, the SAM 440ep's UBoot failed to detect the card properly, meaning that SAM 440ep owners could not use the RadeonHD graphics card driver for Amiga OS 4.x that I am developing.

The problem with the SAM 440ep board was that the Radeon HD PCI cards are actually PCI-Express graphics cards with a buiilt-in PCI-Express-to-PCI bridge. As a result, the card appears as a device behind a bridge to the system. This is the same issue that seems to be preventing Pegasos II users from using the same graphics cards on their system.
With this UBoot update, a large number of Amiga OS 4.x users are now able to use more modern graphics cards. All that remains to be done, is for me to finish the drivers...

It's quoting something that was written on that day, so "this morning" means the morning that it was originally written, not this morning. Hans

Just can't stay away Joined: 12/01/2006 From: Copenhagen, Denmark Comments: 1532	Re: Radeon HD Cards Now Work with the SAM 440ep Motherboard @Mikey_C: It's probably not a good idea to quote a posting from Hans' website without introducing it with e.g. "From Hans de Ruiter's website:" or "Posted by ..." or something, especially when it contains references to "the driver ... that I am developing" - not that we'd suspect you of developing graphics card drivers, of course! And "This morning" was actually ten days ago now, so the original posting date would probably also have been useful as an introduction. I actually zipped over to ACube's site just to make sure they hadn't released yet another UBoot . Sorry, don't mean to nag, just offer some (hopefully constructive) feedback. Best regards, Niels Edit: Oh ... Hans beat me to it

Would it appreciably speed up UAE? Just building on what Antique said, the speed of UAE is dominated by the emulation, not the speed of the graphics system. I wouldn't expect to see any speedup, ignoring the speed of the PCI bus. My primary reason for developing the driver is that I want to eventually be able to use shaders in OpenGL (a long term goal). Plus, we can't rely on old graphics cards forever, and I still expect that we'll get better hardware at some point in the future. Hans

The soldered Sam440ep video card has in fact only 64Mb and it is quite small for a resolution of 1680x1050 or a 1920x1080 (full hd). I now have two video card in my small Sam440ep (PCI 9250 with 128Mb) and I'm really happy, unfortunately I still have issues like: - some demo, game and warp3d stuff doesn't work at all and freeze the system; - the Cygnix package have issues that you need to manually fix - installing the debian linux with two video cards requires you to know how to configure the X sustem

Quite a regular Joined: 03/11/2008 From: Dunedin, New Zealand Comments: 868	Re: Radeon HD Cards Now Work with the SAM 440ep Motherboard Ok, so I want to go buy a new graphic card toy for the SAM Flex with this new uboot installed... What card is available in Kiwiland that I could buy now (technically the best) and put the radeon 128 to one side... And do I need to tweak these settings (running on a 22" LCD) CMPLENGTH=6 BOARDNAME=Radeon VSYNCMIN=56 VSYNCMAX=75 HSYNCMIN=30000 HSYNCMAX=83000 MODE=640x480@60 MODE=800x600@60 MODE=1024x768@60 MODE=1280x1024@60 MODE=1600x1200@60 MODE=1280x720@60 MODE=1440x900@60 MODE=1680x1050@60+RB (MODE=1920x1080@60) (MODE=1920x1200@60) (FAKENATIVEMODES=Yes) (INTERRUPT=Yes) thanks for the insight

I have the EP; wasn't quick enough to snag a flex. So you're in Sandy? Maybe I know you...where you ever in the AUSM users group?

About getting a RadeonHD card in NZ, there is an HD2400 available here. I got my HD 4350 from an Aussie shop (see the last item on the list, here). Just note that users of RadeonHD cards are going to be without 3D support for a while. When it does come, 3D support will probably arrive for Radeon X1550 cards first (it's easier). Those who are looking for a card for everyday use should still stick with Radeon 9000-9250 cards. Hans
