This will give an overall post division by ((1 + 2) * 2) = 6, yielding a bitrate of 4915200 / 16 / 6 = 51200. Compared to that you will get 76800 with a divider setting of 0 like this: ((0 + 2) * 2 = 4, 4915200 / 16 / 4 = 76800. It's not only a problem of speed and fifo depth, but also a problem of integer mathematics. The SAB82532 has an input clock of 29.4912MHz on the Ultras, and also a much more flexible BRG divider section, so it can hit more common baud rates up to B921600 without problems (yes, I tested this).

That symlink is supposed to be in /vmlinuz, since I'm pretty sure your /etc/silo.conf points there instead of /boot/vmlinuz. Check to make sure. You can either make a new link in /, or edit silo.conf to look at the right /boot/vmlinuz. Next set of kernel-images will have the correct symlink.

Upgrading Kernels was yRe: classic & sparc2 install reports
Oddly, when I went from Stable to Frozen in dselect I noticed that there was an SMP kernel available. Whiz, that I am, I thought. Neat - I can just run dselect, reboot, and I'll have a dual processor kernel running. Apparently this is overly optimistic. deslect immediately picked up some libc6 version conflicts, noting that I needed a more recent kernel than I had while running deselect. dselect suggested just getting one from kernel.org. Since I already had the package in /var/cache/apt/archives I tried running "dpkg --install kernel-image-2.2.14..SMP " and to its credit even thought the 2.2.14 kernel is installed in /boot with /boot/vmlinuz poining to it - it still booted up the old 2.0.35 kernel. Can anyone elaborate on the steps I might have overlooked? Should the install and configuration software in dselect be adjusted for people like me?

Well it seems that there is a better example silo.conf for multiple kernels in the silo source. I haven't tried it yet. I was frustrated at the time because I saw references to lilo.conf file format, but couldn't find any documentation on that either. It turns out to have been part of the documentation that didn't install, see below (the dhelp problem). > Also, the version-number extension trick didn't > seem to work for having multiple versions of the > modules directories, on Sparc. How _do_ you have different kernels access different module directories in debian/slink for sparc? For intel, I understand that you just give the kernel an extension, and then give the same extension to the /lib/modules/put_your_extension_here directory hierarchy, and it will all just work. Is it different for sparc, or did I likely just execute it badly (ie, should try again, this time without mistakes :-)? > Well this mail is quite long, I guess I'll leave it at > that.

Well, purging dhelp from my system using dselect resulted in the other three packages (apt, lynx, and a pile of documentation "doc-linux-html" or some such) now installing and configuring, so I have a browser (lynx) and some documentation now. I had thought that I'd have to fix the install scripts for the other three packages to avoid referencing dhelp_parse, but it seems those install scripts check to see if dhelp exists first so that saved me some work. > Also, I installed > libstdc++.2.9 at one point because some other package > depended on it, and that broke my X server.

Well, it was stormy here shortly after that post, and when I re-plugged in my system and it rebooted, the xdm screen appeared like magic, even though I hadn't removed the libstdc++2.9 library off my system. I don't know what happened here. Goodness, now I need sunglasses to look at that login screen :-) > I will address the X server by trying > to uninstall that 2.9 lib.

graphical browser for debian/sparc?
What's a working browser for debian/sparc? I have slink for sparc. I tried running chimera, but it crashes rather a lot. gzilla also crashes a lot. I'd really prefer one that already exists on the slink-for- sparc distribution cd, as my modem is 14.4 K, but I'll download a browser if I have to. Please don't laugh at the question, I never would have noticed gzilla was a browser if I hadn't seen it mentioned in a mailing list somewhere. Perhaps these (gzilla and chimera) are crashing a lot because I don't have them configured right? Any pointers to getting a functional graphical browser going would be appreciated. -- [EMAIL PROTECTED]
problems on SS5/170
Howdy... I've aquired a SS5/170 with 64meg RAM, a 2gig internal drive, a qfe and a PTI SC SI controller[1]. I'm trying to install Potato on it via tfpboot.img from 2.2.1 0-2000-03-30/sun4cdm. I'm using the serial console - the box has a TGX, but I h ave no 13w3 monitor. I made it all the way through the install the first time I tried, using DHCP to configure qfe0 and fetching the drivers, rescue and base via HTTP, using a Squid proxy. Unfortunately, I made / too large and the resulting system wouldn't boo t, so I had to start over. Every subsequent install, the machine has hung at some point. It seems to lock solid, but a break still drops it to the ok prompt. Usually, it hangs while fet ching one of the required files from the network[2], but I've also had it hang a couple of times while untarring base2_2.tgz. As an additional data point, on the subsequent attempts, the drivers, rescue and base came out of the proxy's cache, so they were coming as fast as the SS5 could take them. Is it possible to get to the shell running on tty2 via the serial console? Any hints would be most appreciated.

Re: Zilog 8530 maxspeed?
hm, but what about 57600bps? modems support it, all SW also. Should I believe that Z8530 can do 38400, 76800 but NOT 57600bps? With Siemens 82532 serial controller you can do all speeds w/o any problem (except 76800 of course :) andrej - Quoted message begins - > > Hi all!

Requesting a build of non-free XForms library.
Hello, libforms0.88_0.88.1-3 was uploaded in october and is not in sparc's potato non-free section. As a consequence, sparc doesn't have lyx either (and all other XForms dependent packages in contrib). Could someone build the sparc package? lyx could then also be built by someone (as well as jazip, xwatch, xplot, xcolmix and likely other packages that depend on XForms). The binary is glibc2.0, but I presume that's better than nothing. If someone knows of a glibc2.1 version, let me know. The XForms site didn't have a glibc2.1 version of 0.88 or 0.89 for sparc when I looked, and I can't connect to their web site now (http://bragg.phys.uwm.edu/xforms or http://bloch.phys.uwm.edu/xforms) Thanks, -- Peter Galbraith, research scientist <[EMAIL PROTECTED]> Maurice Lamontagne Institute, Department of Fisheries and Oceans Canada P.O.

kernel compile flags
I would ask this on sparclinux if I thought I would get a response, but my last post there was ignored :( and I don't have an imap newsfolder for them (and don't really want to subscribe) so I can't check whether anyone is actually alive over there... The question is: why do kernels (at least the 2.3 kernels we've been building) seem *all* set to compile with -mno_fpu on sparc? does the kernel support the fpu (i.e. can userland programs use it?) afaik yes is this just a weird issue where the kernel doesn't do any fpu stuff anyhow, and breaks w/o the flag?
