I have two hosts, both using 3Com 3c503 EtherLink II cards and often, the kernel reports that I have a possible conflict on IRQ 5. Since I bought these boards 2nd hand, I don't think I have the full docs for them. Can anyone offer some assistance here? Specifically the info I seek is: 1) general desc of what IRQs are 2) what I must do to the 3c503 cards (jumpers??) to get them on a different IRQ so that they do not conflict. 3) how I can tell what the IRQs are for the other boards in my machines. Any help on any of the above would be greatly appreciated! cak Geekium Rex ------------------------------ From: jhenders@jonh.wimsey.bc.ca (John Henders) Subject: Re: How are the Linux Packages put Together?

One was the problem some sites (like mine) were having with networking, etc. Anyway, I was sure I saw a statement that said the new kernel and other disk changes were now on tsx-11.mit.edu and that the a1.3 and a1.5 images would be updated soon afterwards. I checked today and the a1.* disks are still the old ones? I also checked the ChangeLog file and did see that a lot of the B and C series disks have been reorganized. I would like to start over with my install with this newest release as soon as possible. Could someone tell me when the latest a1.* images will be updated on tsx-11.mit.edu? Thanks for your help!

VESA modes imply BIOS. Protected mode doesn't use the BIOS. Why don't we use the BIOS? Because it's difficult to do at all, and impossible to do portably. XFree86 runs on almost a dozen operating systems, not all of which support V86 mode, and those that do all do it differently. What we do is basically OS-independent. It also is extremely restrictive. Ever seen a BIOS mode for 1152x900? Lots of folks use such a more for X. And that's just mode setting. What about bank switching? Sure, the VESA BIOS provides functions for that. But that would mean a switch to V86 mode for each and every bank switch. I would guess that doing this would cut the server performance in half, if not even more. Why do you think it is that card vendors do their own drivers for Windows? For non-accelerated cards that have a VESA BIOS? Because the performance of a driver for VESA BIOS calls would suck major rocks. The correct solution, which will never happen, is for the vendors to provide SVPMI (SuperVGA Protected Mode Interface) files for their hardware. There's a reason VESA came up with this standard; I wish some of the vendors would follow it. -- David Wexelblat (908) 957-5871 Fax: (908) 957-5305 AT&T Bell Laboratories, 200 Laurel Ave - 3F-428, Middletown, NJ 07748 XFree86 requests should be addressed to "Shining, flying, purple wolfhound, show me where you are."

Better yet, why not form a for-profit company that distributes linux and gnu software for cost only. Then sell support. If you have a problem or a question, buy a service contract for a few months. All profits should be doled out to those that provide the support AND those that do development - not necessarily all under one roof. As for who gets what, I dont think it would be all that difficult to distribute any profits in a meaningful way. Is anyone remotely successful at doing this?

I have a question. Excuse me if there were some similar questions in the past, but at least I couldn't find any similar question or answer in the FAQ list. My qestion is about the WINDOWS API emulator on UNIX-clone systems. I've heard that Sun's WABI, MS-WINDOWS API emulator on Solaris, made it possible to use MS-WINDOWS software on UNIX systems. Usually I make some data on Linux and reboot my PC and then feed them to the Mathematika for WINDOWS. It's very tedious procedure. I think it will save much my time if something like WABI were available on Linux. It may be very meritorious if many MS-WINDOWS programmes were executable on Linux like on OS/2. I would like to know if some development projects for MS-WINDOWS emulator on Linux like dosemu ( or winemu ?) are going on now or not. If it so, by making japanese localized version of winemu, it might be possible to execute some japanese localized Windows programs like MS-WORD, MS-EXCEL, e.t.c. I think it may be very hard task to make winemu comparing with dosemu, since the number of API of Windows are many times larger than that of DOS. It will need much person-power to accomplish such project like winemu.

If you are going to say X runs in 4Meg, tell us what you use and what you do with X. I found X in 8Meg was a bit tiresome when I started doing real development work, running emacs, a couple of gdb's, some xterms and compiling would make my system swap, increasing the RAM to 16Meg made life more comfortable.
