I am going to have to repartition my hard drive and I need to have some idea of how to calculate the size of a swap partition. Does LINUX use the usual UNIX strategy of mapping the available virtual memory onto the swap partition so that the swap partition needs to be at least as large as the core memory or does the swap partition merely hold VM pages which are not currently in core.

Hoffman) Subject: backspace doesn't work with ash: work-around! Date: Wed, 1 Apr 1992 19:55:32 GMT I've noted that, when the backspace doesn't work under a VC with ash, reseting the screen with setterm from another VC tends to fix the problem. E.g., if you're having a problem under /dev/tty1, go into /dev/tty2 and try setterm -reset > /dev/tty1 It's worked for me a few times. Don't know why. -Joel (joel@wam.umd.edu) ------------------------------ From: joel@wam.umd.edu (Joel M. Hoffman) Subject: problems with IO after suspending process Date: Wed, 1 Apr 1992 19:51:45 GMT I've noticed the following annoying behavior with both elvis and gnu-emacs when run from bash: After suspending the process (via ^Z) and then resuming it (with `fg') IO is all wrong. Input isn't recognized until a CR is sent. This looks like a simple bug concerning tty modes, but I don't really know anything about tty modes. (And I don't really believe in ``simple bugs''....) I'm using the bash distributed with 0.12. I haven't been able to find a more recent version. -Joel (joel@wam.umd.edu) ------------------------------ From: smithje@pobox.upenn.edu (Joe Smith) Subject: Re: GCC/Make Probs Date: 1 Apr 92 19:17:00 GMT Reply-To: jes@mbio.med.upenn.edu In article <11601@ucdavis.ucdavis.edu> cccstevn@underdog.ucdavis.edu (Steve Ansell) writes: >In article <0dpt73G00WDJ9O8GAI@andrew.cmu.edu> cd2a+@andrew.cmu.edu (Court Demas) writes: >> >>I posted about this before, but I'm still having problems: >> >>I have installed GCC 1.4 (gccnew) and make (don't remember where it >>came from).

This was the problem when I got that very message. Last night I tracked this down to a bad 'as' (gas) in /usr/bin (untarred from the newgcc.tar.Z file on tsx-11). Although gcc just says 'can't exec...', running 'as' directly gave a memory fault (general protection error). I tried untarring the file with the tar from the 0.95a root floppy as well with the same result. Unpacked on a Sun-3, 'as' is the same size, but gives a different checksum. This isn't really a solution - my plan is to carry the 'as' file home separately tonight. Given the number of bad file transfers people seem to encounter, maybe something like 'zoo' that computes a checksum would be a better means of doing the transfer, at least until 'tar' stabilizes. , richard@robots.oxford.ac.uk (Richard Lewis) writes: > I have a Viglen 386LS (2M RAM, 44M ST-506 Drive, Western Digital > Controller).

LINUX ANSWER: There is no support in LINUX for disk controllers at the secondary controller addresses (yet). Care to write and debug it? DOS ANSWER: I got told by Hard Drives International that the only disk controller that would run with an MFM controller would be a SCSI controller. I do have a friend who is running an ESDI and an IDE concurrently, however. I suspect in reality that it is possible given the following conditions: 1) Run the IDE as the primary disk controller. 2) Setup the CMOS disk drive types to indicate the IDE drives ONLY. If only one IDE drive, set the second disk type to NOT INSTALLED. 3) Strap the MFM contoller to the secondary addresses. (This may not be possible on some MFM controllers. If so, you are SOL) 3a) If both disk controllers have floppy drive support, strap one or the other to the sencondary addresses, or disable one. (If this is not possible, then your floppies will NOT work right!) 4) Run the MFM via a device driver (software required under DOS). I have not seen an IDE controller that can be addressed at the secondary disk controller addresses. If you can find one, you may be able to swap the disk controllers listed above. No, I do not know where to get the device driver software for the secondary controller. BE CAREFUL: I had to upgrade my BIOS in order to run a large capacity IDE drive in my system. (No configurable disk drive type in my disk table). HDI offered to sell me an IDE controller with a BIOS on it instead of me getting a BIOS upgrade (the extra expense in the IDE disk controller was less $$ than the BIOS upgrade), but I opted for the BIOS upgrade anyways.

Swap space expands your available VM -- you don't need to start by allocating the same amount of physical memory. However it's probably still a good idea to have at least that much swap space. If you have 4MB of memory you may be able to exist with no swap space at all. C may run out of memory, but I actually managed to recompile the kernel on a 4MB machine with no swapping. However I think most people recommend that you have at least some swap space available. ------------------------------ From: cm445a17@socrates.umd.edu (cm445a17) Subject: Re: For the PS/2?

Some SCSI adaptors emulate IDE BIOS functions, and will cause problems. Further, some SCSI adaptors (like my Mylex) emulate IDE HARDWARE. I tried to add an IDE drive to my system, and I can tell you from experience that two devices on the bus, both responding to and sending out the same hardware signals, is not too good for your data. Nothing was physically damaged, but I lost 420Mb of data (backed up) and frightened myself, because it took 3 days of experimenting with various utilities to get back the partition table on a SCSI drive that can't be low-level formatted. -Dave -- David Giller, Box 134 | Q: How many Oregonians does it take to screw in a light Occidental College | bulb?
