Ethernet
One 10/100BaseT port supporting IEEE 802.3
Video
Supports CRTs displays with resolutions up to 1600 x 1200 x 24 bpp, and TFT flat
panel displays with resolutions up to 1024 x 768 x 18 bpp.
Audio
AC97 Codec. Stereo input and stereo output.
Watchdog timer
Time-out is 1 second to 2
16
seconds. Strobed through built–in, enhanced
INT 17h function calls.
Real time clock
AT compatible with external battery backup.
Operating systems
The operating systems supported by Octagon Systems are Windows XP, Linux and
DOS.
Power requirements
5V ±0.25V; 1.04A @ 500 MHz with 1 GB DDR memory, typical; 0.84A with 512K
DDR.
Note The power supply for the 5266 must meet the startup risetime requirements
specified in the ATX Power Design Guide, version 1.1, section 3.3.5. This ensures
that all the circuitry on the 5266 sequences properly and avoids system lockup.
Environmental specifications

Micro PC form factor
Weight
8 oz.
Excessive Thermal Stress
This card is guaranteed to operate over the published temperature ranges and
relevant conditions. However, sustained operation near the maximum temperature
specification is not recommended by Octagon or the CPU chip manufacturer due to
well known, thermal related, failure mechanisms. These failure mechanisms,
common to all silicon devices, can reduce the MTBF of the cards. Extended
operation at the lower limits of the temperature ranges has no limitations.
