- Some addendum to a possible problem between the partition switcher OS-BS
- mentioned above and my console driver CODRV:
-
- (excerpt from BUGLIST.151292, only bug added since BUGLIST.011292):
-
- -------
- BUG 14: The old pccons worked. Codrv hangs after showing the Copyright
- message. I use Thomas Wolfram's "os-bs" (osbs-132/134)
- partition switcher.
-
- FIX 14: os-bs is broken in that way that the keyboard character to be
- entered is not correctly removed from the keyboard queue.
- OS-BS does not use, for some unknown reasons, BIOS Interrupt 16h,
- but fiddles with the keyboard controller itself. This causes a
- release code to be left in the keyboard queue, when a selection
- key is pressed. This code irriates the codrv attach routine and
- causes 386bsd to hang. The problem (with a different effect) also
- occurs with OS/2 2.0 with the first keyboard request.
-
- Fix: This should be fixed in OS-BS, but it is unknown whether the
- author is still available.
- The next version of codrv will address this problem for 386bsd.
- Workarounds:
- 1. Make 386bsd the default partition, and let it timeout.
- The effect in other (DOS-type) OS versions is not so extreme
- (mostly additional character at first keyboard access). The
- effect on Linux or other UNIX versions is unknown.
- 2. Use the Mach-Kernel switcher that was posted some time ago
- by Julian (a copy available from e.g. ftp.uni-duisburg.de
- in /pub/unix/386bsd-0.1/unofficial/patches/boot.block). This
- will catch the surplus scancode and has more benefits.
