Hello Matt I did a test by modifying the parameters of the port range in the config.opts. With the values given by "lspci -vv" (1) for the card bus, this is sure, the PCMCIA cards don't work. With the values given by WinXP (2) , they work. In details : (1) with lspci -vv : I/O window 0: 0000c000-0000c7ff I/O window 1: 0000c800-0000cfff ....... I/O window 0: 0000b000-0000b7ff I/O window 1: 0000b800-0000bfff These values put in the config.opts file : # d'apres lspci -vv, valeurs decomposees en 4 gammes include port 0xb000-0xb7ff include port 0xb800-0xbfff include port 0xc000-0xc7ff include port 0xc800-0xcfff (2) with Win XP, the values put in the config.opts file : # d'apres WinXP, valeurs decomposees en 4 gammes include port 0xcc00-0xccff include port 0xd000-0xd0ff include port 0xd400-0xd4ff include port 0xdc00-0xdcff For the two tested cases, the memory range is in the config.opts file the following : # d'apres WinXP : include memory 0xfa200000-0xfeafcfff These are the values given by Win XP such as : #include 0xfa200000-0xfa200fff #include 0xfb200000-0xfd1fffff #include 0xfd200000-0xfd200fff #include 0xfdaf5000-0xfeaf4fff #include 0xfeaf5000-0xfeaf5fff #include 0xfeaf6000-0xfeaf6fff #include 0xfeaf7000-0xfeaf7fff #include 0xfeafc000-0xfeafcfff If I use the values of the PCI bridge secondary=02 (include memory 0xf8a00000-0xfeafffff) or of the two Cardbus (include memory 0xf8a00000-0xfd1ff000) : it does not work. I know that this is very curious but I am sure now that this is the only way to get the PCMCIA card working. How to explain ? I don't know :-) ! Kind regards Pascal
