You might also want to try a CF to ATA adapter which is what I am using to boot Devil Linux from a CF card. All they are are small PC boards with the correct connectors to allow the CF device to be plugged into a standard motherboard ATA hard drive connector. They also require power, normally from a standard 3 1/2" power supply connector (not SATA) because the standard MB ATA connector does not have power pins. After that they look just like a normal hard drive to the OS so no unusual drivers are needed. I have been using onefor quite a while now with no problems. I did a quick check on Ebay and they are available for about $7 USD with shipping included, They are also available from more local suppliers but they usually cost between $10 and $15. I use a Secure Digital card connected to the computer using a USB card reader for the configuration file because it has a write protect tab and mounts read-only with the tab in the locked position. The only time this device is mounted (mine shows up as /dev/sda1 using fdisk, the CF card shows up as /dev/hda1) is when the computer is booting or while the save-config script is running so it can be removed, unlocked/locked, and re-installed, as needed. One note of caution. Not all USB card readers report the state of the lock tab and none of them that I've seen advertise if they do or not. It is easy enough to find out if they do or not but not until after you bought it which I found out the hard way of course :( ---- Andrzej Odyniec <an...@ma...> wrote: > Jan Hugo Prins wrote: > Hi Andrzej, > > >>This is probably a completely new motherboard (by the way, show off what the MBs). >> > > > Not completely new.

This driver is by default compiled with the kernel as a module. >> Dear Jan Hugo, Well, a quick installation guide has nothing about the CF controller. We also have a question: how long will live capacitors on the board, since it already has six years? I was expecting, CF controller is connected as Mass Storage device via USB but you can see that it does not. However, the scenario is as described, which means that the initial stage of the boot is missing appropriate driver and the kernel does not see CF card. When later CD is mounted and all modules are present in filesystems, udev loads the appropriate drivers and CF card will be displayed. You need to determine which module is responsible for access to CF eg reading lspci, lsmod, watching /proc/bus, /proc/scsi etc under full system (when a CD is already mounted (with the default configuration or the configuration loaded from the CD as well) and CF is visible. As you suspected a module, remove it using rmmod and then check whether the device CF disappeared and then load it back using modprobe and check if it had come again. Then you can try to compile the apropriate driver as linked statically into the kernel. This is simplest way; when driver is linked into the kernel, device is present immediatelly after kernel is loaded, without modules from initrd and explicite loading this modules by init script. If you are not prepared for such a compilation, let me know about needed module and I will try to compile an experimental mod for you.
