[B2-devel] OS X CDROM problems

[Nigel P. <ni...@in...>]

	I am working on the CDROM parts of sys_unix.cpp for Mac OS X,
but haven't gotten them to work yet. Annoyingly, Apple has different
IOCTLs to FreeBSD and NetBSD.

	The strange thing is that the DEBUG results I am getting are =
similar,
but slightly different to, the Linux ones:

7.1 install disk on Intel Linux:
...
CDROMOpen
  DrvSts at 00003f08
  TOC: 00140101 00140100
  Lead-Out M 9 S 10 F 65
  HFS partition found at 65536, 156270 blocks
  adding drive 2

Same CD on OS X:
...
CDROMOpen
  DrvSts at 00003e00
ioctl(DKIOCCDREADTOC) read 20 bytes
  TOC: 00120101 00140100
  Lead-Out M 0 S 160 F 205
Looking for HFS partitions on CD-ROM...
  block 0, signature '=00=B7' (00ff)
  block 1, signature '=00=00' (0000)
...


	Note that the second byte of the TOC differs. Any ideas?
