1 Introduction This manual describes the Soekris Engineering net4501 Series of boards and systems. The net4501 is available as a board only, or in a small sheet metal case. In both cases, they are available in different configurations. The net4501 is based on the ElanSC520 embedded processor from AMD, and is basically a PC compatible embedded computer optimized for network and communication applications.
Integrated in the ElanSC520. Main Memory 16-64 Mbyte PC100 SDRAM, soldered on board. BIOS 128 Kbyte FLASH, soldered on board. Contain Soekris Engineering comBIOS. Bus Expansion 1 - PCI slot, 3.3V only, limited power available. 1 - Mini-PCI type IIIA socket. Ethernet Up to three Ethernet Controllers using the National Semiconductor DP83815 PCI busmaster chip, supporting 10BaseT and 100BaseT.
3 BIOS 3.1 Overview The net4501 comes with the Soekris Engineering netBIOS. The BIOS is designed especially for setup and operation using the serial port as the console. The BIOS is located in Flash memory, and can be upgraded over the serial port. Critical system setup parameters are also saved in the Flash memory, so the system will not lose any setup information due to CMOS battery backup power loss.
not detect the start of a XMODEM transfer. Downloaded binary image will be saved in memory at 4000:0000. flashupdate Update the system flash BIOS with image at 4000:0000, normally the one just downloaded using the “download” command. time [HH:MM:SS] Update the time in the battery backed Real Time Clock, or if no parameter, show the current date and time. The time should be entered in 24 hours format, as “hour:minutes:seconds”.
Serial Console speed baud rate. Value can be 2400, 4800, 9600, 19200, 38400 or 57600, default is 19200. ConLock Protecting the serial console port from modifications using int14 system calls. Value can be “enabled” or “disabled”, default is “enabled”. Useful for preventing MS-DOS from changing the console speed on start BIOSentry To control if the “Press Ctrl-P for entering Monitor.”...
4.1 J1, DC Input Jack The 2.1mm DC Power Jack should be used for connecting a small wall mount unregulated power adapter, supplying 9V-12V DC at 10 VA, with a 5.5mm outside, 2.1mm inside female power plug with plus at center pin.
Function Pin Number VPWR GPIO 4 GPIO 0 4.9 JP10, Reset 2 pins 0.050” header. Shorting the two pins together will hard reset the board. 4.10 JP11, COM2 10 pins 0.050” header for serial port COM2. Can be connected to a DB9 using a de facto standard cable assembly.

CompactFlash adapter or a USB based reader/writer. Differences in sector translation using IDE devices can complicate doing the loading on another system. The net4501 uses a simple algorithm for sector translation, if there are less than 1024 tracks, it will use the native CHS that the CompactFlash reports, if more than 1024 tracks, it will use LBA translation.
