Seen with FC4T2 and latest FC4T3nightly (2005-05-08). See these pages for more details: http://www.yellowdoglinux.com/support/solutions/ydl_3.0/dual-drive-fix.shtml http://lists.terrasoftsolutions.com/pipermail/yellowdog-general/2003-April/007186.html Even though I have elected _NOT_ to touch /dev/hda, the first partition on /dev/hda changes from type "Apple_partition_map" to type "Apple_Bootstrap" after install of FC4. No data is touched, simply the partition type is changed. This renders OS X unbootable as OS X does not recognize any partitions on the system after this change has occurred. The only method to recover your system is to change that type back with a hacked copy of 'pdisk'. Disk layout _before_ install, from OS X's pdisk command: /dev/rdisk1 == /dev/hda (ATA Master) /dev/rdisk0 == /dev/hdb (ATA Slave) /dev/rdisk1 map block size=512 #: type name length base ( size ) 1: Apple_partition_map Apple 63 @ 1 2: Apple_Driver43*Macintosh 54 @ 64 3: Apple_Driver43*Macintosh 74 @ 118 4: Apple_Driver_ATA*Macintosh 54 @ 192 5: Apple_Driver_ATA*Macintosh 74 @ 246 6: Apple_FWDriver Macintosh 200 @ 320 7: Apple_Driver_IOKit Macintosh 512 @ 520 8: Apple_Patches Patch Partition 512 @ 1032 9: Apple_HFS Untitled 12330982 @ 1544 ( 5.9G) 10: Apple_Free 10 @ 12332526 Device block size=512, Number of Blocks=12594960 DeviceType=0x0, DeviceId=0x0 Drivers- 1: @ 64 for 23, type=0x1 2: @ 118 for 36, type=0xffff 3: @ 192 for 21, type=0x701 4: @ 246 for 34, type=0xf8ff /dev/rdisk0 map block size=512 #: type name length base ( size ) 1: Apple_partition_map Apple 63 @ 1 2: Apple_Driver43*Macintosh 56 @ 64 3: Apple_Driver43*Macintosh 56 @ 120 4: Apple_Driver_ATA*Macintosh 56 @ 176 5: Apple_Driver_ATA*Macintosh 56 @ 232 6: Apple_FWDriver Macintosh 512 @ 288 7: Apple_Driver_IOKit Macintosh 512 @ 800 8: Apple_Patches Patch Partition 512 @ 1312 9: Apple_Free 0+@ 1824 10: Apple_HFS Apple_HFS_Untitled_3 39815104 @ 263968 ( 19.0G) 11: Apple_Free 0+@ 40079072 Device block size=512, Number of Blocks=40079088 DeviceType=0x0, DeviceId=0x0 Drivers- 1: @ 64 for 23, type=0x1 2: @ 120 for 36, type=0xffff 3: @ 176 for 21, type=0x701 4: @ 232 for 34, type=0xf8ff
Steps: /dev/hda = OS X drive /dev/hdb = future Fedora Core drive 1) Normal install until Disk Partitioning Setup screen 2) Choose Autopartition 3) Select "Remove all partitions on this system" 4) Deselect /dev/hda (OS X drive) 5) Check "Review and modify if needed" 6) Next 7) Note hda shows 128M free space errantly 8) continue as normal to standard packages, next 9) note error in anaconda.log following enablefilesystems 10) dialog - Partition Map has no Partition Map Entry 11) pdisk shows hda1 changed to Apple_Bootstrap
Should be fixed in rawhide
