This version is very nice. It still has the old sign-on message which needs to be changed. I noticed this BIOS has a physical sector cache which is a major saving in latency during consecutive sector reads. Only one physical sector read per 4 logical sectors. Also the IDE addressing is done with the OFF parameter which makes formatting generically possible. The BDOS and CCP are separate from the BIOS which is less likely to accidentally change the BDOS or CCP. This BIOS consolidates ROM RAM Floppy IDE ATAPI VDU and DSKY all in one BIOS with floppy interrupts.

This is identical to John's release except that it builds on Mac OS X for Mac users.
