Question: RH6.1 with 2.2.14 

Forum: PCMCIA Installation and Configuration Issues

From: Duane Gustavus duane

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 kernel build: 2.2.14 #2 Sun Mar 12 15:36:18 CST 2000 options: [pci] [cardbus] [pnp] PCI routing table version 1.0 at 0xf0b40 unknown PCI interrupt router 10b9:1533 PnP: PNP BIOS installation structure at 0xc00fcfb0 PnP: PNP BIOS version 1.0, entry at f0000:cfe0, dseg at f0000 Intel PCIC probe: VIA VT83C469 ISA-to-PCMCIA at port 0x3e0 ofs 0x00 host opts [0]: none host opts [1]: none ISA irqs (default) = 10 polling interval = 1000 ms I have the PnP OS BIOS value set to no, and the secondary IDE controller disabled (the DC wants to use that).

Checksum 0x00 (OK) # 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

That's a new one Re: Question: RH6.1 with 2.2.14 (Duane Gustavus) Date: 2000, Mar 14 From: David Hinds <dhinds@pcmcia.sourceforge.org>

I have not seen that error message before. Could you try doing "strace -f cardmgr" and send me the output? Were you invoking cardmgr as root? Is there anything else "odd" about this system setup? -- Dave

It was a filesystem permissions issue Re: Question: RH6.1 with 2.2.14 (Duane Gustavus) Date: 2000, Mar 15 From: David Hinds <dhinds@pcmcia.sourceforge.org>

The problem was that /var was mounted "nodev", and cardmgr attempts to create a device file in /tmp, which was linked to /var/tmp. I will either fix cardmgr to do this differently or at least document the requirement in the man page. -- Dave

Ok: Antec DataChute notes Re: Question: RH6.1 with 2.2.14 (Duane Gustavus) Date: 2000, Mar 15 From: Duane Gustavus duane

Hello, I just spent a long weekend and more getting pcmcia services running on my RedHat Linux system using the 2.2.14 kernel and pcmcia-services 3.1.12. I thought I would relate a few issues that might be of help to others (a trail of crumbs in the darksome forest as it were). I am using an Antec DataChute ISA-PCMCIA device in my desktop. This device uses a VIA VT83C469 chip which is evidently compatible with the i82365 (ie it seems to work with the flash card I am using). It also expects to be the secondary IDE controller, so you will need to disable the secondary IDE controller on your motherboard to make it happy (yes that means you will have to move any IDE devices currently on the secondary channel off). My /etc/sysconfig/pcmcia file looks like: PCMCIA=yes PCIC=i82365 PCIC_OPTS="irq_list=10,11 has_ring=0" CORE_OPTS= CARDMGR_OPTS= The PCIC_OPTS line is set to the IRQs I want the adapter to use (in other words, you may well wish to change this). This is a PnP board, so while I set my BIOS to answer NO to the PnP OS question, I built an entry for isapnp.conf using pnpdump. I was able to comment out the IO line because it was causing problems during boot. If you don't use a PnP card, you will avoid this hassle. Through the good offices of David Hinds, the last problem squashed was the mount specification for /tmp. I always use a separate partition for /tmp with the nosuid and nodev mount options for security purposes. The cardmgr makes a couple of device files in /tmp which will of course fail if you use the nodev option. David is considering the relocation of those files, but if you use the nodev mount option, you will need to make sure cardmgr doesn't try to open it's device files in that particular partition. I would like to thank David Hinds for his speedy response to my m'aidez, not to mention the quick isolation of my problem. I hope these notes are of use to the next person down this path. Cheers, Duane
