Bassano del Grappa, Italy - 06 Dec, 2020

ACube Systems is happy to announce the availability of another update to UBoot firmware for the Sam440ep, Sam440-Flex and Sam440-Flex SE.


Our commitment to the Amiga Community is still strong as it was at the beginning of our adventure, and it will bring more news in the upcoming year.

This release, a “Christmas gift” to all our customers, brings the following enhancements and fixes:

U-boot 1.3.1g — Dec 04, 2020

Improved support for Radeon HD and Radeon RX graphic cards.
Now you can use a Radeon HD / RX via a PCI to PCI Express adapter. On the Sam440ep flex motherboard, it is recommended to use PCI slot #1 for maximum performance. Please note that full support for Radeon RX is still under development and for this reason, with many models of gfx cards, U-Boot does not show any output, but the card works fine once the operating system is loaded.
     
Introduced a new menu entry to change the x86 gfx BIOS emulator accuracy.
If your graphic card show some visual problems on startup, try increasing the x86 BIOS emulator accuracy.
     
As always, read carefully the instructions in the archive.

You can find the updates on Sam440ep (http://www.acube-systems.biz/index.php?page=hardware&pid=1) and Sam440ep-Flex (http://www.acube-systems.biz/index.php?page=hardware&pid=2) product pages.

We hope you will enjoy this update.

Stay tuned for other news in the upcoming months.

Thanks, Lecta, cool!

On a plain Sam440ep (with the built-in graphics) it doesn't sound like there's anything of benefit in this update, is that correct?

Best regards,

Niels

This cable is a little more expensive but the PCIe socket is mounted at a right angle to the PCB so you could mount it to the inside of the case using standoffs although you'll probably need to drill and tap your own holes to screw the standoffs into.

How about this, does these PCI to PCIe brides support 66mhz / 2x speed? Or do I need a PCIx to PCIe bridge?

Is there a Radeon HD basic driver in Sam 440 install media, to make testing easier??

I posted it in the Amigaworld thread but it may be useful to other users here too.

A PCI to PCIe x16 adapter with the PEX 8112 bridge chip is recommended and the is code in the Radeon HD driver to oprimise the settings of the chip.

I remember that this board has some issues displaying full hd (1920x1080) via DVI. Is this still true or does it work flawlessly nowadays?
