Dropping ethernet connection

Question

 

I am running XPe on a compact flash in a pc104 computer.  The computer has two ethernet ports.  Both ports work but sometimes upon booting, one of the ports (always the same one) disappears.  Anyone know what might cause this?  Could it have something to do with timing and BIOS enumeration?  I have not been able to repeat this problem using a PC104 harddrive running Full XP on same machine.

Answer 1

 

It could be timing with the flash. Try a different CF with DMA to see if that works. WinSystems (http://www.seanliming.com/flashhelp.html) has some CF cards with DMA support.

 

It could also be a faulty driver. Please make sure you have  the latest drivers for the system.

 

Also, PC104 has some peculiar characteristics. If you stack the PC104 cards in different orders the results will be different. This is a cause of the capacitance loading on the bus.
