I have a few questions concerning XENIX. We are running XENIX System V on a genuine IBM AT, equiped with two 30Mbyte fixed disks, and 2.5Mbytes of RAM. My first question is on that second disk, which was only recently installed. When XENIX boots, at some point the following is displayed : | The IBM Personal Computer XENIX | Version 2.00 | (c) Copyright IBM Corp. 1984, 1985 | (c) Copyright Microsoft Corp. 1983, 1984, 1985 | | Reserved Memory = 2K | Kernel Memory = 176K | Buffers = 100K | User Memory = 2282K | bad signature (B66D) on drive 1 | | Type Ctrl-d to proceed with normal startup, | (or give root password for system maintenance):_ | My question is now : what does the BAD SIGNATURE message really mean, and how do I get this fixed. I must say that the second disk is not currently in use for XENIX, (or anything), so we just put one large DOS partition on it for testing. It seems to work just fine. Also, the diagnostics program on the diagnostics diskette delivered with the AT shows no errors. My second question concerns the configuration of the XENIX kernel. We are using the XENIX system as a development system for network drivers. This means we are adding several device drivers to it, (for PCnet, ethernet, and in the near future Token Ring), and we are currently adding gateway software to the system. Now we also use some XENIX System III (which is XENIX 1.) systems, om which the same software is added. What I'd like to know more about is the kernel memory assignment. In the configuration files, a lot of parameters are set, concerning things such as kernel buffers for IPC, and for disk access (if I recall correctly). Does anybody know what these parameters exactly mean ? We don't use the IPC facilities such as messages or shared memory. Do you know a way to get the buffers for these things out of our new kernels ? Basically : is it safe to put a zero value for some of these 'tunable parameters' ? Please mail your answers directly to me. I will summarize on the net. Thanks everybody.

I`m looking for information on the details of the SLIP protocol. In particular, does anyone know of a PC/MS-DOS implementation? If not, papers about SLIP will suffice. Thanks! R. Murphy

Hi, In the package pcnfs from Sun you have the possibility to use telnet, ftp and nfs over an asynchronus line (SLIP). I know that there is a slip package available for the PC . I am not quit sur but in the package pc/tcp from FTP software this was available. regards, Franck Masson Prime France

Its good - I used it to succesfully connect various "socket" programs connected through a Cisco terminal server (running SLIP) to a Unix box connected through TCP/IP at 2400 baud. I can dig out their phone number if needed. ---Ashmeet sidana@cs.stanford.edu sidana@hpcc01.hp.com Disclaimers: This should be not be considered an endorsement of any company mentioned above by HP or Stanford.
