Some people call _this_ interoperability= =2E I'd concerned about breaking configurations that use 0x85 for something else. Even if it is for a Linux extended partition, recognizing it will reorder the slice numbers for logical drives within ordinary extended partitions if the Linux one is scanned first. > BTW, to my knowledge, extended linux partitions were used (in place of 0x= 05) > to prevent certain versions of dos fdisk from crashing when it tries to > follow beyond cyl 1024, that is, to preserve compatibility.

I sometimes boot DOS-4.1 (1988 version), and it is certainly confused by cylinders beyond 1024, but using magic extended partition types wouldn't help much because it is the primary partitions beyond cylinder 1024 that cause the biggest problems :-). Do you know which versions of Linux default to using 0x85? The version of Linux fdisk that I have handy (built on Apr 23 1997) doesn't mention partition 0x85, but IIRC the Linux kernel support for partition 0x85 is older.
