WINE actually runs simple dos programs like pkunzip or command.com :) but it
needs a lot of work which is actually happening anyway by the time you are
reading this. In order to get dos running you have to emulate int21 (Dos
services) and most of the Bios interrupts. Also you need to virtualize a large
number of I/O ports. All these are very well documented at
http://ctyme.com/rbrown.htm
Alternatively you can try running DosEmu/Bochs/VMWare but you will still need to
purchase a licensee for the Microsoft DOS version ?? or you can try FreeDOs.
As you can see there are plenty of options for almost every point of view or
possible need.

Subject: Redhat 6.0 and glibc-2.1 src rpm rants
Date: Tue, 18 May 1999 16:05:36 GMT
Okay, someone correct me if I'm wrong here but the ideal behind src
rpms is that you can just do a rpm --rebuild on the src rpm and get the
binary rpms. Now I ask you does this make sense. You put out a rpm in
the RPM directory and on the same archive you put the src rpm in the
SRPMS directory. You do this with the understanding that the package
in the RPM direcotry is build from the package in the SRPM directory.
So you should be able to build binary package A from src package B.
Okay, so RH compiles glibc-2.1 in 6.0 with the debug shit turned on
totally confusing my debugger and anoying the hell out of me. No
problem I say, I just grab the src package and recompile like I've did
with every other freak rh release. Based on my understanding in
paragraph one I should not see this when trying to recompile glibc-2.1
from the source package?

Subject: question about proto_init()
Date: Tue, 18 May 1999 14:39:31 GMT
Hi,
looking at the network stuff in the linux kernel I ran into
the following problem. The function proto_init() calls init functions
for each protocol family known to the kernel:
void __init proto_init(void)
{
extern struct net_proto protocols[]; /* Network protocols
*/
struct net_proto *pro;
/* Kick all configured protocols. */
pro = protocols;
while (pro->name != NULL)
{
(*pro->init_func)(pro);
pro++;
}
/* We're all done... */
}
Now my problem is that I do not find the place where the struct
protocols[] is initialized. It must be filled with some values before
this function is called obviously. Can you point me to a place in the
kernel where to look for that?
Also I do not quite understand what the "__init" in the function
declaration actually means.
Thank you very much for your help!

Dear Alex,
I have a customer that can't get the PCIS-DASKNT software to operate
with his 7300A card.
When he attempts to start the 7300A device in control panel, it returns
an error message that says not enough resources available (Error 1450).
It is acting like there is no interrupts available even though it is the
only card in the system.
Any suggestions?
Robert.

I'm pretty sure it was 2.1, but I got it from rawhide using rpmfind, so it
could've been a beta of some sort. Actually, when I ran into that
__setfpucw problem, a search on dejanews turned up __setfpucw being
mentioned in this thread, so I guess the real release also has this
problem.

Well, I changed your path to "/dev/ttySL0", and it worked fine...
so I took my device array and plugged into your program and
everything worked fine!!
Could the problem have anything to do with the fact that I
was doing readdir() calls during this?? Would that affect the
results of calling stat()?? That's the only difference that I can
see between your code and mine... However, I was printing
out the value of the strings that I was passing to stat(), and
they were correct, fully-qualified paths...
I'm still mystified...

The newest mpg123 sources have a MMX-module (or was is 3D now? ) - anyway, for

Which is the best flavor of LifeSavers? It's a matter of taste. For ease

Redhat, Debian and SuSe, not in any particular order. If you want to

to use and very fast, and it doesn't try to impress you with a GUI for
this and that.
The final issue is support, check the standard and available support
since you consider yourself a novice and are doing a bunch of systems.
There are no "bad" distributions, there are only ones which think the
way you do. I suggest you buy the sampler pack from CheapBytes, for
about $5 for three CDs, and try a few installs. I currently have
Slackware (mostly), Redhat, Mandrake and SuSE running on various
machines I admin or use, some were installed just for experience, but I
didn't find any reason to install something else.

Subject: boot/root disk problem with login
Date: Tue, 18 May 1999 15:14:13 -0400
Hello All:
I need some help. I'm making a boot & root disk combination for some
utility uses, and I'm having a problem with /bin/login.
Here's what happens:
1) I boot my kernel off a boot disk.
2) It asks for the root disk, which I give it.
3) It reads the root disk and init starts.
4) Init runs /bin/hostname and /sbin/ldconfig and then hands off to
getty
5) Getty prompts me for a login
6) I type in my username and login asks me for a password and I *always*
get a "login incorrect" messeage.
Stuff I've tried:
I have tried this with root with a password and with no password.
I have tried this with a user account with a password and no password.
I have made sure that /etc/securetty exists and has tty1 in it and that
inittab starts getty on tty1
I have recompiled login, getty, and init from source, ensuring they
don't need any bizarre PAM stuff.
I have run ldd on init, login, hostname, ldconfig, and getty to make
sure those libraries which they report dependancies on exist on the root
disk.
I have insured that the utmp/wtmp/lastlog files are where login expects
them.
Can someone offer me some suggestions about what's going wrong !?! I'm
mystified!
Thanks,
Stu

Subject: gdb, threads, and Red Hat Linux 6.0
Date: 18 May 1999 12:45:10 -0700
Hi,
I'm hoping this is the right place to post... let me know if someplace else
would have been more appropriate.
We're using Red Hat Linux 6.0 out of the box, no special patches or
upgrades, and having problems with threads not freeing up process table
slots when run under gdb.
The attached program generates four threads which all immediately exit.
When run standalone from the shell, there are two PIDs devoted to my
program, as there should be (one for the main thread, and one for the
thread manager). When run from gdb, however, the same two threads show
up, along with four processes in the zombie state, even though the
threads are all created with the PTHREAD_CREATE_DETACHED flag in their
attributes.
Has anyone else experienced this? Is there a fix?
Thanks much,
~Ben

Date: Tue, 18 May 1999 22:37:28 +0200
Hi all,
i ad set up a diskles X-erminal th SuSE5.1 which had kernel 2.0.32 and
work fine. Now I want to upgrade to SuSE6.1 both the server and the
client. All runs fine so far except the client doesn't boot. The reason
is that the BOIOTP request doesn't reach the dhcpd of the server. I can
see in /var/log/messages the DHCP-request of the bootprom, and the
tftp-requests of the used bootstrapper up to the point where the kernel
vmlinuz is delivered. I can see the delivered kernel boot up to the
BOOTP-request which isn't seen in /var/log/messages and times out.
I tried kernel 2.0.36 and kernel 2.2.5 with same result. The old 2.0.32
works fine.
Is this a bug in the new kernel versions or what could be the reason ?
Thanks for your help.

Odd, because the tulip.c file in both these kernels sport "v0.89H".
You don't think the kernel developers would hack the driver and not
change the version number, do you? That would just add insult to

This suggests that if you are upgrading you do it one at a time, or at
least a few at a time until you have some faith in the software. Also, I
always build a new kernel and modules and unstall them without touching
the old version, then add a stanza to the lilo.conf and run LILO. This
lets me boot the new kernel *by hand* and be secure that the old kernel
will boot the next time if the machine rolls over.
I have toy machines which run the latest kernel while the bits are still
hot, but my production stuff doesn't get updated unless there is some
reason. I still have several 2.0.33 machines, one 2.0.37pre10 (until
SCSI is fixed in 2.2), one 2.1.131 and one 1.2.13 which has been up for
years.
