There isn't much on the boards to identify them except NEC Home Electronic (USA) Inc. mva 1024 rev3 assy 22800 The board has a TMS 34010 and three gate arrays (??) marked Paradise plus a bunch of 41464 and 41264 RAM and a DB-9 connector. Does anybody know what type of video cards they are. Does a driver for Linux exist if not would it be worth while to write one?

Please do not crosspost anything between different groups of the comp.os.linux hierarchy. See Matt Welsh's introduction to the hierarchy, posted weekly. If you have a question about Linux you should get and read the Linux Frequently Asked Questions with Answers list from sunsite.unc.edu, in /pub/Linux/docs, or from another Linux FTP site. It is also posted periodically to c.o.l.announce. In particular, read the question `You still haven't answered my question!' The FAQ will refer you to the Linux HOWTOs (more detailed descriptions of particular topics) found in the HOWTO directory in the same place. Then you should consider posting to comp.os.linux.help - not comp.os.linux.misc.

The problem is that you mention "xv". My experience shows that you can't avoid swapping when you run xv on e.g. a 640x400 (or larger) image, esp. when it tries to do some processing. The consequence is that it's sloooow. Everything else apart from graphics processing is perfectly acceptable. When I compile a large file with gcc something which is not in use may get swapped out (e.g. some xterm, xman, ...) but swapping it in again when I want to use it is quite fast (i.e. in the 1-second range). So basically the conclusion is: Don't expect good performance for interactive graphics, but most other tasks will fit fine into 8 MB RAM. > MB"). (Note: I will probably be using a Western Digital 420MB 12ms > IDE drive, in case that matters for swap speed) No it doesn't matter. Swapping is always slow, no matter whether you have a 30 ms drive or a 12 ms drive. Swapping is only acceptable for removing *unused* pages from RAM, but a task running interactively should never be swapped out. If this happens, you should definitely get yourself more RAM (instead of a faster drive :-) Andreas. =============================================================================== Andreas NEUBACHER, Research Institute for Symbolic Computation, Johannes Kepler University, 4040 Linz, Austria. aneubach@risc.uni-linz.ac.at !Packed signature! ------------------------------ From: balister@maddog.async.vt.edu (Philip Balister) Subject: Re: Reminiscence...

Through, trial and error I have managed to jumper the board to COM3/COM4/LPT2, and can talk to the board fine as evidenced by my modem dialing, however I never receive any echo or data back from the board. I have verified both the cable to my modem and the cable from the board connector out to the D-shell using my other comm board. Both DOS and Linux recognize the com ports at the right addresses and irqs. The second parallel port works like a champ. The board has a label of "CT-450" and does have 16550s on it. On the outside edge of the card are the connectors for ribbon cables for the 2 serial ports and 2 sets of jumpers. The left set is labeled S2 and had 6 positions. The right set is labeled S1 and has 4 positions. Through trial and error I have figured out that the right 3 positions on S1 control setting the serial and parallel ports to be at COM1/3, COM2/4, and LPT1/2 respectivly. As I said above I can send data to the COM3 or COM4 ports but never recieve any data back. If anyone out there has a similar board and can provide the jumper settings or any suggestions I would be most appreciative. Please reply via E-mail as I don't read these groups that often and I will summarize to the net if there is any interest. Thanks. -- David W.

My installation notes and first-pass evaluation follows: Bringing Linux/SLS up on Handbook 486. I have the 40MH DX2 handbook with the 130MB hard drive. I decided to give linux an 90MB partition, plus 4MB for swapping, and leave the rest for a DOS partition. If you only have 4MB of RAM, you must create a swap partition or install will not run. I tried the base + X installation with an 80M partition (it allegedly only needs 70) but it took 78M and filled the filesystem, so I tried again with 90M. If X doesnt' work I'll repartition again and make the linux partition much smaller. You really need the external floppy drive for this operation, don't rely on the emergency boot partition (I believe it gets wiped out by linux's fdisk, at least I tried to switch to it after running fdisk, just to see if it was there, and I couldn't boot). create the main and swap partitions with fdisk you will get an error message from fdisk from the large partition - ignore it. change partition type for 1 to 83h - Linux Extended mke2fs -c /dev/hda1 90000 if you get an error about no place to put inodes or some such, you forgot to make the partition type 83 instead of 81 (the default). mkswap /dev/hda2 10350 (number reported by fdisk for this partition) swapon /dev/hda2 now you can run install... doinstall /dev/hda1 swap disks till you run out... if install asks for disks, then never accesses the drive, you forgot to tell it to swap. For some inexplicable reason, the zImage that SLS installs on your HD and on the boot disk hangs during booting. The zImage on the floppy disk works fine - they are different sizes btw. I managed to get it to boot from the harddrive by copying in the zImage from the install disk. I am rather disturbed that I had to do this, and I'm thinking of reinstalling with Slackware, but at least I know Linux works on this machine (so I don't need to worry about whether to send it back). To copy the zImage from the install disk: Boot from the a1.3 disk, when you see the word LILO hit alt type harddisk root=/dev/PART (where PART is your root partition, /dev/hda1 is the default) log in as root mkdir floppy mount /dev/fd0 /floppy cp zImage zImage.bak cp /floppy/zImage zImage shutdown and reboot. Linux should come up just fine. You will need to add the swap partition to the /etc/fstab file, the install doesn't do this for you - add the following line: /dev/hda2 none swap defaults Observations so far - it feels fairly zippy, except when you are waiting for the hard drive to spin up. If you are running off the AC adapter, you can set the power manager to optimal performance so this will not be a problem. The boot process reports 19.97 Bogomips (for whatever that's worth - it's a bit faster than my 33/486 desktop which is as it should be). I haven't gotten X configured yet - more notes to follow when I do. I periodically get error messages "Unexpected HD interrupt" - I'm not sure what causes it, but it doesn't seem to cause any harm, the machine keeps right on going. There is a fairly serious problem with the resume feature - namely if the machine has been suspended for more than a few minutes it spontaniously reboots when it resumes. This is bad under DOS, really bad for Windows, and a major lose for Unix, for obvious reasons. The temporary fix is to at least sync the disk, preferably shutdown before closing the box. I hear rumors of a flash BIOS upgrade that addresses this problem, I'll look into it. All in all I'm pretty happy despite the problems. I had to expect some difficulties if I insisted on being on the 'bleeding edge' :-) - At least to me it's worth some trouble to have a unix system that fits in my purse and is light enough to carry everywhere, I can do a lot of stuff offline instead of snarfing a modem on panix for hours at a time. -Liz -- Liz Stokes | Ilaine's E-Z Garb Workshop ...
