Why did the 1024 limit start? Well, the MSDOS defined partition table layout only allows 10bit cylinder numbers. So I could see if the machine was going to have DOS and XENIX partitions using the disk to stick with the MSDOS partition table layout. However, if someone wnated a XENIX only machine shouldn't XENIX be easily able to do its own hard disk boot sector to handle a partition table layout that is different? And since XENIX is contained within one physical partition that then has logical partitions.... John H.
