Message:

Devices/PC/BIOS/eltorito.c: Don't use the skip_b, skip_a mechanism for accessing arbitrary 512 byte sectors inside a 2048 byte CD sector for the emulation code but rather chop up the transfer into at most 3 separate ones to handle unaligned cases. This enables cleanups in the device drivers which comes next, bugref:4841 [fix]
