...ES, DI, at least when using a partitionless HDD, causing "Boot error" from the magic check as it was loaded to the wrong location. HPA suggested wrapping INT 13h with the push/pop for ES's safety. This then lead to checking over for all int 13h calls in diskstart.inc to try and use xint13 and no net increase in binary code size. Then, the Sect1Ptr values were made constants by reference and the boot sector code was split into a new file (so it can be reused by debugging/diagnostic images; Yes, I'm already using it). -- -Gene
