Why was NCP removed in 1.1.48?
Too alpha to end up in 1.2.0, or did Novell threaten to sue? :(
(Not that I persoanlly need it, far from it, but I want to know if
Linux is being threatened by the Novell Empire or whether it is something

I have a similiar problem.
I turned on the IDE (WD-1003/ST-506) emulation mode of my DPT SCSI card so
that I can install Slackware 2.0 and patch the kernel to include the alpha
SCSI driver for EATA card. However, when boot up Slackware 2.0 boot disk,
it gave me the following message.
hd.c: ST-506 interface disk with more than 16 heads detected,
probably due to non-standard sector translation. Giving up.
(disk 0; cyl=950, sect=32, head=64)
The cylinders, sectors, heads, are whatever I enter into CMOS setup. My
harddrive is a Micropolis 2112 with logical disk geometry 1001 cyl x 64
heads x 32 sec/track. I enter 950 cylinders into CMOS just to avoid
confusing fdisk. However, it didn't work either, whether it's over 1000
cylinders or not.
fdisk just gave me "Unable to access /dev/hda".
The physical disk geometry is 1744 cyl x 15 heads x VAR sec/trk.
Anyone has any idea why Slackware gives me that message? Is it an error
message?
Thanks in advance for helping get into the Linux community.

Subject: time speeds up
Date: 1 Sep 1994 14:49:54 GMT
Has anyone experienced the clock running abnormally fast? I set the correct
time, have had the system up for 1 week or so and the time is now almost
15 mins fast. I gain about 2 mins a day for no apparent reason. This has
been happening with kernel versions going way back (pre-0.99.10), I've
reported this before but didn't get any response. Is this only happening
to me? I'm running 1.1.48 but I don't expect patch49 to have a fix. Is
there something obvious that I've overlooked? BTW, as a check, the system
has recently sat at the MSDOS prompt for over 4 days and *lost* only 1 sec.
The board is a 386-40/256k cache/387 with 32M. This has been happening with
1 IDE drive, ATIXL card, and simple multi-io. Now the equipment connected
are 2 IDE drives, ATI Ultra card, 4-16550 card. Still nothing out of the
ordinary as far as I can tell. I'll have to do some deep digging this
weekend. I'm getting fed up having to adjust the clock so often (I know
there're services for dialin date/time retrieival but that's not the point).
A side question: In the kernel sources, what's the "HZ" constant for? Any
chance this could be the culprit?

Any chance both your SCSI card and Ethernet cards are bus mastering cards
in an ISA chasis? I understand that multiple bus masters from differing
vendors is a big no-no. The manual from my Novell-Eagle NE-2100 doesn't
even permit multiple NE-2100's in the same machine. Then again, this may
not apply to Linux.
I know enough of the ISA bus to be dangerous. It would appear that multiple
bus masters should work as bus access is arbitrated thru the DMA controller.
Maybe someone could address this issue?

What? I was unaware that any company was still making such slow
machines. You can get a VL bus motherboard with MIPS R4600 processor
that makes Pentium look like a 4.77 8086. Why waste money on such
a junky architecture as Intel when there are good processors available.

Compare the price/performance of processors and Intel comes out to
make the worst processors in existence. PowerPC chips provide twice
the performance of Pentium at half the cost. That means they are
4 times as good. PowerPC is considered slow compared to some other
processors on the market. For myself, I am just trying to decide
which non-Intel motherboard to get. They do not cost anywhere near
$10K.

make zlilo will do all of the following:
1. make zImage
2. mv zImage /vmlinuz
3. lilo
I think that is what you mean, and it is already available. Time for

Which version of the kernel are you running?
The behavior of getty_ps when dialing-out/exiting/reinitting the modem changed
(I believe) with the advent of the new serial drivers in 1.1.13?-18. After
a uucico or cu exits, uugetty does not get triggered to re-init the modem
reliably. For me, it does answer the phone and all that, but if a prior
dial-out turned off ATS0=1, well, it's all over.
Something must be different when DTR toggles, but I can't even speculate
what.

Very cool. Do these work the same way as in BSD 4.4? How can we access
these new features? I seem to remember reading that under BSD the immutable
files can only be modified in single-user mode. Is it necessary to be in
single-user to remove the immutable attribute as mentioned above? I think
this would probably be a good idea. Thoughts?

Sure! I've given up trying to convert the average user.... if they
are comfortable with Lotus 123 and WordPerfect 5|5.1|5.2|6.0 or
Word, or whatever, let the have them. If we don't have the same
tool available on Linux and it won't run in dosemu or iBCS, let
them be... you know what they say about trying to teach a pig
to sing.... :) You can, however, install one of the PD NFS
clients to link their PCs to your Linux Host for file backup,
security, program and data storage, etc.
As Linux gains in popularity (check out the number of articles now
appearing about it!), those vendors intelligent enough to take
advantage of a developing market will make their products available
on Linux platforms also. There is no need for us to reinvent the
wheel, so to speak. One commercial product that is available now
and is very good (particularly at the DOS business target) is the
Flagship Database development system. This allows you to develop
and port your xBASE and Clipper applications to Linux (native!)
with all the wonderful tools and functions you're used to in the
equivalent DOS products with the advantage of being multi-user,
supporting the PC console as well as X-terminals and regular
dumb terminals, and generating good solid sellable applications.
It's not free; but they do have a special introductory offer for
Linux users as a trial balloon... you can bet other vendors are
watching! You don't need the manual (built in help screens,
etc.) but it's handy to have. There's even a free demo version
available via ftp. If things like this keep being ported to
Linux native and we support them with our $$$ rather than wanting
the world but not being willing to pay for it (waiting until
the ubiquitous "someone" develops it for Linux) I think we'll see
these products appearing. Of course, they will cost money, just
like their DOS counterparts.... I think sometimes we've gotten
so spoiled by "free" software that we are worse than the MS-DOS
"pirates" who trade copies of Lotus and WP around instead of
buying their own! (I'm gonna get flamed for that one, aren't I?
Just a couple of cents worth...

There are at least two freely available user-level thread packages for
Linux available. Kernel threads are being talked over/worked on, but
are not available yet. Here's an older posting pointing to the user-level

Well, I've been running 1.1.47 for about a week now without any trouble.
I've used SLIP, PPP, iBCS, WINE, X, and a bunch of other stuff fairly
heavily, and no problems. So not everyone is having trouble. It depends
on what hardware you have, no doubt. Mine is a plain-jane 486/33 w. 8MB,
AMI BIOS, and two IDE hard drives. Solid as a rock.
