SVN rev 189749 on 2009-03-12 20:41:52Z by jhb
The recent change to use memory > 1MB for the heap by default broke CD
booting because the CD driver did not use bounce buffers to ensure
request buffers sent to the BIOS were always in the first 1MB. Copy over
the bounce buffer logic from the BIOS disk driver (minus the 64k boundary
code for floppies) to fix this.
