Hi - Thanks - this is helpful (I'm a novice at BIOS details). Here's what I see with > d 400 0000:0400 F8 03 00 00 00 00 00 00 00 00 00 00 00 00 00 9B Looks like 0x03fe is correct for the first uart (/dev/ttyS0), but all zeros after that (starting at 0:402h). Looks like the BIOS isn't setting the second uart? I'm using netBIOS 1.41c.

I don't have net6501 to check, but i have i wonder what bios > data table at address 0:402h shows. > -- » Toby Schneider « » Oceanographic Engineer « » GobySoft, LLC « » [email protected] « » 1.508.289.1716 « » http://gobysoft.org « _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
