Cna anyone answer these questions? (SysV,v.3.0): 1) Is it possible to set ulimit globally, to be something other than 2048 ? Currently, only setuid root can take advantage of a changed ulimit, and only for subshells. I added a ulimit = 8192 statement in kernel config file, but ulimit is still 2048 for everyone (incl. root). My motivation for changing ulimit is the transfer of > 1 Meg files by users - currently not possible, unless setuid root. 2) If I don't use the -f option of F77, the program core dumps (illegal instruction) on execution. Works fine with -f. I have configured for MAU, and it is shown as included when /etc/system is run (in firmware). cc doesn't complain. I assume that cc automagically chooses emulation/MAU ? F77 doesn't work with MAU ? 3) Lastly - when I remake Unix using /etc/system - I get two undefined variables, but unix is made, and bootable. Is this common ? Can it be fixed without calling AT&T $ervice hotline? Thanks for any, and all answers! Mike Finegan mfinegan@uceng.UC.EDU

Here are the steps to making changes to the UN*X kernel for the AT&T 3B2: 1. Edit the /etc/master.d/kernel file, make changes as appropriate. 2. Change directory to the /boot directory and type: mkboot -k KERNEL 3. Change directory to the / directory and make a copy of the current version of the kernel, just in case. For example, cp /unix /Ounix 4. Shut the system down to firmware mode and enter: /etc/system as the name of the program to boot from. This will then cause your changes to be incorporated into the kernel. > 3) Lastly - when I remake Unix using /etc/system - I get two > undefined variables, but unix is made, and bootable.

In /etc/system, you may find entries such as: INCLUDE:MAU INCLUDE:IDISK . . . etc, make sure that a file, similarly named, exists in /boot. If not, then comment out or delete the reference in the /etc/system file. =============================================================================== Philip A.
