At the risk of preventing this mail thread dying a natural death:
For a bootable device the following must hold true:
a) BIOS level support must exist for the device interface
b) The BIOS support must place hooks into INT13
Practically ALL parallel port devices fail item "a" since the code to
access the device is not available.
The only device that passes item "a" that I know of is the "ZIP Plus"
only because it can plug onto a SCSI card (hence this is cheating :-)
Just because the interface has BIOS support does not mean it can
boot from it. An example of this is some SCSI cards will only boot
devices set at ID=0, the "external SCSI" ZIP drives can only use IDs
5 or 6.
If someone is feeling insane I am more than happy to help them
code up the BIOS level support for the parallel port ZIP drive.
Most network cards have a slot for a boot prom, in theory there
is nothing preventing(*) this being used for "other purposes"
such as booting from a parallel port device.
PS: Grant, I will be freeing myself up for some serious kernel
(*) Some network cards impose an 8/16k window, therefore a
reduced driver only supporting SPP may be required.

up on your C programming and help improve the kernel."
