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. ----- Holger -- | | / Dr. Holger Veit | INTERNET: veit@du9ds3.fb9dv.uni-duisburg.de |__| / University of Duisburg | | | / Dept. of Electr.
