Problem in SCO Release Supplement 5.0.4c The SCO 5.0.4c release supplement has a bug that will cause the text based screens to not display a login prompt if you have a DAC in your system. To get around this problem you can login on the graphical screen (), type "ps -ef | more", find the process that is "defunct" and kill that processes parent by typing "kill -9 " where is the parents process id. You have have to do this each time you reboot the system. Contact SCO Support for the latest information on this bug. Release Supplement 5.0.5a Fixes SMP and IRQ Sharing Issues If you are running SCO OpenServer 5.0.5 you should install SCO Release Supplement 5.0.5a (or later) to your system. RS 505a fixes a number of networking, multi-processor, and IRQ sharing issues. RS 505a must be installed after SCO SMP support is installed. Please see the release notes for RS 505a on the SCO web site for more details. Floppy Read or Write Errors If you experience read or write errors on the floppy drive you may want to tune the floppy controller driver. To do this follow these steps. Edit the file /etc/conf/pack.d/fd/space.c and locate the last two lines. Modify them in the following way: Change: int fd_enable_FIFO = 0; int fd_FIFOthresh = 0; to: int fd_enable_FIFO = 1; int fd_FIFOthresh = 1; Then relink the kernel and reboot the system.
