Ethernet
Note To avoid possible hardware damage, only use a 3.3-volt card; the DP83815-based NetGear FA-312 is recommended. |
Geode-based SDBs support the National Semiconductor DP83815 (NetGear FA-312), RealTek RTL8139, any SMC9000-compatible Ethernet card, and any NE2000-compatible Ethernet card | Debug Ethernet card and product Ethernet |
| Serial | 3 on the main board, 2 on the low pin count (LPC) card | Port 1 on the main board is used for OEM debug output; two serial ports on LPC card are supported |
| PCMCIA or CF | 1 CF | Not applicable – boot only |
| Mouse | PS/2 | Yes |
| Keyboard | PS/2 | Yes |
| Cold boot hardware reset | Yes | Yes |
| Warm boot hardware reset | Yes | Yes |
| Warm boot software reset | Yes | Yes |
| Touch controller | Yes | No |
| Universal serial bus (USB) host | 3 | Yes |
| USB function | PCI | PCI Netchip 2890 |
| Serial Infrared (SIR) | Yes | Yes |
| Fast Infrared (FIR) | No | No |
| Audio output | Yes | Yes |
| Audio input | Yes | Yes |
| Parallel for printing | 1 | Yes |
| Integrated Device Electronics (IDE) | 1 | Yes |
| Smart card | USA and PCMCIA | No |
| IEEE 1394 | PCI | No |
| Floppy disk | Yes | No |
| TV output | No | No |
| Floating point unit | Yes | Yes |
| Expansion connector | PCI | Yes |
| PCI slots | 2, ISA not supported | Yes |
| Compact PCI or PCI extender | No | No |
| Logic analyzer probes | No | Not applicable |
| JTAG | No | Not applicable |
| Debug LEDs | Yes | No |
| Companion or add-on cards | No | Not applicable |
| Form factor | ATX | Not applicable |
Note The PCI slots on the National Geode SP4SC30 Development Platform are 3.3-volt slots. Plugging a 5-volt PCI card into either PCI slot permanently damages the National Geode SP4SC30 Development Platform. If it looks like a card is being plugged in backwards, it is being done incorrectly. Always use the Babel interposer card that is packaged with the National Geode SP4SC30 Development Platform to install a 5 V PCI card into the National Geode SP4SC30 Development Platform.
National Geode SP4SC30 Development Platform Hardware Restrictions and Limitations
- In cases where a PCI extender does not work in the system, see the platform vendor for a BIOS update.
