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.
