The loopback interface could have IP address 127.0.0.1 and connect to a loopback network 127.0.0.0 with netmask 255.0.0.0 (conceptually) About assigning the same IP address to multiple interfaces on the same host: One could argue that this is "correct" as long as the outer world cannot see any difference. Consider all interfaces as one big specially designed interface with the software (linux) hiding the differences. So, as long as the software supports this concept it is correct IMHO. ______________________________________________________________________ Frank van Maarseveen _____ _ _ fvm@tasking.nl Tasking BV /_ / |_/ / Plotterweg 31 / \/_/ _/ phone : +31 33 558584 Amersfoort, The Netherlands fax : +31 33 550033 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When I hear of Schrodingers cat, I reach for my gun --- S.

It is just too big and clumsy. NEXTSTEP is undeniably the finest operating system I have ever used. The user interface is intelligently thought out, the operating system is object oriented from the ground up, and the application development tools were the first of their kind. I have an original NeXT box on my desk for doing day-to-day office tasks like mail, remote logins, word processing and spreadsheets. I also upgraded a while back with their NeXTdimension color card, which increases my workspace by adding a color monitor (better for graphics) next to the original monochrome (better for text). Operating System upgrades and Software installation are a snap. As for memory requirements, 8 megs is too little, 16 enough for most work, and 32 is perfect. The 105 MB disks shipped with the newer workstations was too small, but 330 MB can support the entire suite of development tools and a few extras like Tetris. One area where the NeXT's weren't too strong was add-on cards, a problem surely remedied by the 486 port. Unfortunately, only a limited number of configurations are officially supported, and device drivers for special cards are harder to come by. I once hired a consultant to adapt a PC ISA bus camera controller card to work in the NeXT, but it was expensive and the prototype ended up being the only one ever built. The driver was also difficult, and required inside information from NeXT on how their kernel worked. Most people won't be in this situation, however. Ironically, since our new project required a PC and a custom processing card, Linux was suggested by a co-worker and presents a serious challenge to NEXTSTEP. It enjoys a rapidly widening user base and is at an exciting time in its growth curve. Although I'm no fan of X, Linux provides as generic a software platform as can be had, and all sorts of software is supported. We also have quite a few in-house X applications that would be nice to run without having to run an X server atop NeXT's Display Postscript engine. NeXT was light years ahead of the competition when they came out, and I hope they stay aggressive for the future without letting the industry standards overtake them.

Yes, I know that all the limitations are due to the driver. Under DOS/Windows the Mitsumi can read anything. I don't plan on using photo CDs in the near future anyways. By the time I need to use one maybe it will be supported. I bought the Mitsumi yesterday. Installed like a charm. Kernel recompile was simple as always. I am listening to 'from the cradel' by Eric clapton with WorkMan as I type this. Very nice program by the way. I got the Mitsumi because it is a bit cheaper here but more because the Mitsumi's seek time (1/3 stroke) is 250ms and full stroke is 380ms. The Panasonic's 1/3 stroke is 380ms. This is a big difference. No, I didn't do any side by side benchmarks on it, I'm going on spec sheets here. Anyways, I am happy with my purchase and would like to thank all who offered their advice. If anyone needs to beta test new Mitsumi drivers, drop me a note and I'll be happy to do some tiger testing. Harry -- <:-{} hpulley@uoguelph.ca |This message released|It takes all kinds, \ Harry C.

Not necessarily. Many PCI systems include the NCR SDMS BIOS code in the system BIOS, although they don't include the chip. It would be worthwhile doing a strings /dev/mem | grep -i ncr to see what your memory looks like. >Who makes such beasts? If you need one with a BIOS chip, Nextor's model 93 is the only one I'm aware of, unless you want to go with an 825 based board (FAST+WIDE, requires two minor patches to make it work under Linux). If not, ASUS, Intel, Portland, and many others make non-BIOS equipped boards. >Second, the ASUS card is $100. That is cheaper than many cheapo ISA >cards. Actually, you can find non-BIOS versions of the boards for about $70. Given the fact that many BIOS vendors (ie, Intel) who lacked NCR SDMS support for their boards have upgraded their newer ROM images to included it, this _might_ be the way to go (some of the ROM vendors can't seem to get their act together, and alternate between working and broken releases). Also, any problems caused by flakey protected mode PCI BIOSes should be fixed if you upgrade. The Nextor boards tend to run about $140ish. >Does this mean it is programmed IO? Nope, they're busmastering. Architecturally, they're similar to the Adaptec AIC-7770/7870 chips used on the 2xxx series, except they execute more complicated instructions from main memory rather than simpler ones from on-chip RAM, context switch in software rather than hardware, and have other minor differences. >As of now, adaptec isn't an option for me because of their nondisclosure >crap. Note that Adaptec doesn't have an NDA requirement on the hardware docs as is generally believed, although there is one on the downloadable firmware's interface. However, some of their tech support staff will lie to you about that fact and refuse to forward your calls to some one who knows what's going on. IMHO, that's still plenty of reason to avoid Adaptec. >Buslogic is an option, but they are expensive, and I want to see >if they are worth three times the NCR price. The Linux Buslogic drivers are a bit more mature. If you want top performance from _multiple_ devices accessed at the same time under Linux, right now instead of whenever I get arround to it (I need to finish debugging the new save/restore pointers code so the right values get restored after a SCSI context switch) you'll be happier with the Buslogic boards. People've had a lot of problems with the NCR boards, the vast majority of which break down into general PCI configuration/bug things. I've seen the same sorts of reports in large numbers with the Buslogic boards as well - you'll have it if you have broken PCI devices or a broken mainboard no matter what you use. -- Since our leaders won't respect The Constitution, the highest law of our country, you can't expect them to obey lesser laws of any country.
