[B2-devel] Re: OS X CDROM problems

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

	Thanks Christian. That info was helpful. It is now closer.
After a little extra debug in read_toc(), and an extra flag in the=20
ioctl():


7.1 install disk on Intel Linux:
...
CDROMOpen
   DrvSts at 00003f08
   TOC: 00140101 0014010000000200 0014AA0000090A41
   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 0014010000000200 0014aa0000090a41
  Lead-Out M 9 S 10 F 65
Looking for HFS partitions on CD-ROM...
  block 0, signature '=00=B7' (00ff)
  block 1, signature '=00=00' (0000)



	So, it has valid TOC info, but never finds a valid HFS =
signature.

	That would seem to indicate that the data being read by =
Sys_read()
is bad, but I find that very unlikely. Any thoughts to save me having
to dump and compare 32KB of data?
