booting ide flash from latest etherboot (CVS)

[Ronald G Minnich]

It has a problem getting to flash, but it actually got worse. It doesn't
see the flash disk at all in this version.

To sum up:
fallback + rc4.eb5 -- finds disk, boots it automatically
normal + rc4.eb5 -- type 'D' to it, then it finds disk and boots
normal + rc5     -- never finds the disk, although BBOT_FIRST is to to
			BOOT_DISK

I bet there's some other config thing I've missed.
