Introduction
Your Sam460ex board is ready to go.
Just connect a hard drive, monitor, mouse and keyboard, and switch it on!
It can be housed into a flex-ATX, micro-ATX or full ATX computer case.
The use of a good quality ATX power supply is strongly advised for a correct operation of the
board.

Boot
The current U-Boot version supports booting from the following devices:
- SATA hard disk connected on the onboard SATA2 controller port J15 (* check notes)
- PATA hard disk and/or DVD connected to a Silicon Image 0680 controller on PCI slot (*)
- SATA hard disk and/or DVD connected to a Silicon Image 3512 controller on PCI slot (*)
- SATA hard disk and/or DVD connected to a Silicon Image 3114 controller on PCI slot (*)
- USB mass storage
- internal SD card reader J31
- Network
(*) check page 7 on how to recognize a suitable PCI card for your Sam460ex
Video output
The current U-Boot version supports video output from:
- onboard SM502 VGA port
- Radeon card on PCI slot
- Radeon card on PCI-Express slot
To change the preferred video output, select it from the “Video Option” U-Boot menu.
To suppress most of the boot messages, select “Silent” in the “Console” U-Boot menu.
Notes
1 - the SATA2 port and the PCI-e 1x slot are mutually exclusive, only one of them can be used
at a time:
•to use the SATA2 port, close J16 with a jumper, and select the corresponding entry
in the
“PCI-E 1x / SATA-2” U-Boot menu.
•to use the PCI-e 1x slot, remove the J16 jumper, and select the corresponding entry
in the
“PCI-E 1x / SATA-2” U-Boot menu.
A reboot is required.
2 - the Sam460ex board is built to work standalone in a fanless enviroment but particular care
must be taken when housing the board in a closed metalic cabinet with other electronic
devices (such as hard drives, CD/DVD, DC-DC converter etc..)
In these cases, ensure to have free circulation of fresh air inside the cabinet, via holes or a
small fan.
3- when using a PCI-Express graphic card, we suggest to use a Radeon HD2400 or newer
models. Older models like X600, X800 are not fully compatible with the Sam460ex and may
not work. Some X1550 cards are reported to work OK.
4– after switching OFF the board, it's strongly advised to wait at least 15 seconds before
switching it ON again, otherwise the onboard devices may not work correctly. The current
firmware doesn't allow to switch on the board again after 3 seconds.
5– the onboard graphic card has a maximum resolution of 1280x1024 pixels (4:3) or
1440x900 pixels (16:9).
Supports DDC, 2D hardware acceleration, hardware sprites (3 colors) and PIP.
There is no support for 3D or compositing.
Some operating systems may limit the color resolution to 8 and 16 bits.
Frequently Asked Questions
How to use more than one SATA drive?
The Sam460ex is made both for embedded and consumer markets. It can be adapted to
different needs. As an example, a customer who wants a board for home use will probably
choose to add a SATA controller on a PCI card. This will allow up to four SATA drives. ACube
may provide such expansion boards.
How can the operating system be loaded?
It is possible to load the operating system from a PATA/SATA harddisk, a CDROM connected
on PATA/SATA, an USB key, a SD card or from the network.
How to enable DMA for SATA devices?
Check the documentation which comes with the operating system on how to enable DMA for
SATA devices. By default, all devices are set to PIO mode (slow).
