Document known unbootable media

Description

Some CD-ROM types are bootable in theory, but unsupported by the CD. Examples:

  • PCMCIA drives
  • Drives connected to SCSI controllers that require firmware

We need to document unfixable cases.

Since booting from PCMCIA and having the possibility of CIS updates (needed for some Ethernet cards) conflict (because non-modular firmware loader cannot work), booting from PCMCIA will not be supported.

As for SCSI controllers that require firmware, the reason for their non-support is that, with the current initramfs structure with static device nodes, binary /init and no udev, it is impossible to load firmware at boot time.

ping.

Any changes in the above? It's been open for a year. I'll work on improving the situation but I need a status update first.

The SCSI firmware should no longer be an issue. PCMCIA can be solved by a small change to the initramfs - but I can't test.

I have a laptop with PCMCIA, but I have no PCMCIA CD drive. Anyone out there have one that they can use to help test our CD?
