Changeset 624 in xtideuniversalbios

Message:

Changes:

  • The BIOS version string has been changed to show the repository revision number instead of the useless "v2.0.0 beta 3+" string. In other words, the seemingly never ending beta is finally over! The version string is now updated by TortoiseSVN client side hook scripts (residing in \Tools) to be used when committing changes to the repository. It should also be possible to use these scripts with other subversion clients under Windows since they are essentially just regular batch (cmd) files!
  • The eSEG_STR macro has been changed to always disable interrupts. The workaround used for the buggy, early revisions of the 8088/8086 CPUs apparently does not work. Many thanks to Jim Leonard (Trixter) for reporting this problem!
  • Minor optimizations to the eBSF and eBSR macros.
