Peter, I appreciate your feedbak. Do you know of a specifc BIOS that support routing the PORT 80 to the Serial Port? As far as the OS level it will not work since the POST codes need to be pumbed into the Serial interface long before BIOS hand over control to the OS.

On the OS level you could easily do that in software. not a big deal. If you do not want to have software involved (e.g. your BIOS does not support the redirection), you could do an FPGA design which grabs the Port 80 IO writes and sends it out through an integrated UART. If your not familiar with FPGA design, we could do that for you. We could also attach the chip to the PCI interface. This approach is a little bit mor straight forward. the whole thing were a single chip solution (e.g. TQF144 package for PCI) and cost would be below 10 $. Development cost would be too high because we have long years experience in FPGA / embedded PC design. regards, Peter Marek c/o MarekMicro GmbH Fuggerstr. 9 D-92224 Amberg Phone: +49-9621-9732-110 Fax: +49-9621-9732-199 ################################################### BESUCHEN SIE UNS AUF DER EMBEDDED WORLD 2004 HALLE 12.0, STAND 453 ################################################### ----- Original Message ----- From: Hora Abu To: pci-sig Sent: Wednesday, December 03, 2003 10:14 PM Subject: urgent: LPC to RS232 converter Hi experts, Does any one know of a ?chip? or a solution that can converter LPC bus transaction to a serial RS232 stream? I am looking to integrate such solution on computer motherboards. I have considered a PCI to RS232 cards but due to the volume this approach was cost prohibitive. To give you a background: I need to send the PORT 80 POST codes from my motherboard to a remote system for debug purposes. The only interface with the remote system is done via an RS232. My ideal solution is one small size chip I cannot on the motherboard with an RS232 circuit and this solution will not require any software development (at least not on my part). Sorry if I was not entirely clear for I am an analog engineer. Thanks in advance for your help Aragan --------------------------------- Do you Yahoo!? Protect your identity with Yahoo!
