Hello,
I am having problems getting PCMCIA services to work on my Redhat 6.1 Linux desktop system. I recently bought a "DataChute" ISA-PCMCIA controller which uses a VIA VT83C469. First, I did a new installation of RH6.1 on a spare pentium system, booted the new install and edited the /etc/sysconfig/pcmcia file to say yes. I then shutdown, put the adapter in the system and rebooted. The pcmcia services were started correctly, and I made a file system on a flash card just to make sure. Everything worked as advertised. Next I put the same adapter into my "development" system which is also RH6.1 but upgraded to kernel 2.2.14 and pcmcia-cs-3.1.12. This system has the identical motherboard, but a faster K6 processor. Also, this system has had several different kernel builds done on it (ie is not pristine with the distribution kernel). When I install the 2.2.14 kernel with modules and then the 3.1.12 modules, I have the following results from dmesg:
Linux PCMCIA Card Services 3.1.12

I have the PnP OS BIOS value set to no, and the secondary IDE controller disabled (the DC wants to use that). If I issue an lsmod command, it shows:

Mar 12 16:07:57 marvin cardmgr[366]: exiting Finally, since this controller is a PnP device, I used pnpdump to build /etc/isapnp.conf that looks like this:

# Returns all cards to the "Wait for Key" state (WAITFORKEY) I commented out the (IO ...) line above because it seemed to always have problems checking the device range (causing isapnp to abort execution). Obviously, the distribution RH kernel (2.2.12-20) has some option turned on that I am unaware of, or there is some configuration I have done incorrectly. Sorry for the length of this message; I just wanted to provide enough information to encourage someone knowledgeable to give me some pointers. I really need to have confidence I can build new kernels with the pcmcia services working as I want to put Linux on a PC/104 computer on my robot which will only have pcmcia periperhals. Thanks, Duane duane@denton.com
