Forum: PCMCIA ATA/IDE Device Issues
Re: Question Compact Flash on single-board computers

If this is the only PCMCIA device you'll be using, then you probably
do not need to use any Linux PCMCIA drivers at all... in fact, using
them will only make your life more difficult.  The reason is that
booting is a BIOS function, not a kernel function: if your BIOS knows
how to configure and boot from the CompactFlash slot, then when the
Linux kernel gets control, the card should already be set up to look
like an ordinary IDE device.

If you then want the Linux PCMCIA system to manage that slot, then
things get complicated... because the slot is already "live", and in
fact, the device is probably already mounted as your root filesystem.
There isn't much that the PCMCIA drivers can do to help: you can't hot
swap that card, for instance.  The socket driver tries to recognize
this situation and will leave this slot alone.
