The other point to remember is that some BIOSes think (for reasons
|
||
best known to themselves) that you might not want to cache all your
|
||
RAM. If you have one of these, you have to make sure that you have
|
||
told the BIOS to cache all your RAM and not just the first part. (AMI
|
||
is like this, as I found out the hard way a while ago.)

|

|

|

Well put, although not _entirely_ accurate, but in essence, correct.
|
||
Some bios (AMI, as an example) allow you to determine how much RAM
|
||
to cache. Some don't (Bummer).
|
||
|
||
Also, alot of hardware designs have very lousey design for DMA above
|
||
16 Megs, (read that as: if it's a 386 or if its a mature 486, don't
|
||
expect DMA above 16 Megs.) Most high speed I/O may want to use
|
||
DMA to memory rather than the old 'Test-n-Transfer' mode. (This
|
||
applies to the BIOS drivers for floppies {Yes, floppies} and
|
||
hard drives.)
|
||
|
||
The Pentium grade machines and some of the later '486 designs now
|
||
allow DMA above 16 Megs. Cache for these machines are larger in
|
||
size and allow cache'ng for more than 16 Meg ram.

|
||
Date: 23 Sep 1994 16:25:50 GMT
|
||
|
||
Dear netters
|
||
|
||
Could some kind soul please explain 'term' to me?
|
||
|
||
I have managed to build and run term ver. 2.1.1, and I am able to
|
||
telnet from my local machine to a remote machine on campus. I do the
|
||
following:
|
||
|
||
tredir 2023 remotehost.ucs.edu:23
|
||
telnet localhost 2023
|
||
|
||
this will give me a telnet session on the remote host! good, but what
|
||
if I want to telnet to another host? Same questions regarding ftp.
|
||
|
||
What is the difference between
|
||
|
||
'tredir 2023 remotehost.ucsb.edu:23' and
|
||
'tredir 2023 23' ?
|
||
|
||
How do I use a name server ? can I use 'tredir 2042 nameserver:42' ?
|
||
|
||
I would like to run mosaic from home, I tried to run mosaic on the
|
||
remote computer using txconn, and that worked, but running an x-server
|
||
over a 14.400 modem is not exactly flying. I know that this is a little
|
||
premature, since I have not ftp'ed mosaic yet (I can't ftp to
|
||
ncsa... yet, you know) what do I need to get mosaic to work with term?
|
||
Which docs are a good starting point ?
|
||
|
||
I think my problems stem from the fact that I don't fully understand
|
||
'term'. I have tried to read the README, INSTALL, term.HOWTO, and the
|
||
tcp/ip chapter in "Essential System Administration". If some of you
|
||
could try explain term or answer my concrete problems I will be very
|
||
great-full. Any pointer to further docs on term are also appreciated.

||

||
sincerely Lars L. Madsen

Well, there probably won't be. MCA is a joke. Newer designs exist that

give more throughput (local bus, for example) than MCA ever did. Besides,

the support for MCA, even in the DOS or hardware arena, is rather minimal.

Well, in all of this you have to realize that Linux is an evolving thing.

|
||
|
||
This is fairly easy. There is no need for a HOWTO.
|
||
|
||
Since you are asking how to setup a modem . . . .
|
||
|
||
Make sure that the modems present the proper status of DCD, CTS, and
|
||
DSR. Ensure that the modems honor DTR and RTS. Don't use a cheap
|
||
cable which does not pass these signals.
|
||
|
||
Now, if you wanted to know how to setup PPP for use . . .
|
||
|
||
Read the files README and README.linux in the source package. If you
|
||
have questions about specific sections in the documentation, I'll be
|
||
happy to answer them.
|
||
|
||
Please quote the section that you don't understand so that I know what
|
||
must be changed.
|
||
|
||
The documentation in the PPP is not designed to be an all-encompassing
|
||
PPP document. Nor is it meant to be the general discussion on how to
|
||
set up your network configuration. There are other documents for
|
||
those.
|
||
|
||
The README file is generated by the package author, Paul
|
||
Mackerras. The README.linux file is brought to you by the linux PPP
|
||
working group.
|
||
|
||
You will find additional information in the Networking Admin Guide and
|
||
the NET-2-HOWTO. Please look there as well.
|
||
|
||
I am sorry to simply say RTFM, but, in the case of "gee, I just was
|
||
using vt100 terminal connections and I would like to use PPP. How do I
|
||
do it?" is too broad of a question to answer specifically. So, please
|
||
Read The Fine Manuals. A great deal of time was put into writing them.

This doesn't belong here, really, but hey, neither did the above article.
|

|
||
The Compaq name tag buys you one thing that *could* be worth the money.
|
||
|
||
Customer service.
|
||
|
||
I bought a used Compaq 386DX20. Old machine when I bought it, extremely
|
||
expensive when it was new, I'm sure. After I'd had it a year or two,
|
||
I wanted to install a 3.5 inch drive. Bought one, and the durn thing
|
||
would work. Took it back, got another, and it wouldn't work.
|
||
|
||
Called Compaq customer service. The guy on the other side of the phone
|
||
was *extremely* helpful, and further, he *overnighted*, at no cost to
|
||
me, Compaq installation disks, a manual, and some other PC programs by
|
||
Compaq.
|
||
|
||
That little trick bought them a friend for life. I piece together my
|
||
own systems now, but I'll recommend Compaq to people who want a good
|
||
system and can afford a little extra for it.

Yup! Got one in front of me that does more than 200Mb/sec (64 bits wide)

|

|
||
Someone mailed me and said that the PCI bus on my pentium system
|
||
is 32 bits and capable of 132 Mb/sec.
|
||
|
||
This may well be correct and the PCI bus is probably what we are
|
||
talking about.
|
||
|
||
However, I'm primarily concerned about the bandwidth of the onboard DRAM.
|
||
This IS 64 bits wide and is interleaved in two-bank blocks.
|
||
Does any one know if there is a separate bus for the DRAM?
|
||
|
||
I did some benchmarks some time ago that seemed
|
||
to indicate more then 200 Mb/s but I could have f**ked someting up ...
|
||
(like not using enough working set size to trick the cache ...)

|

: No one. The SGI you are describing is outdated and not sold anymore.

: Funny how a top of the line PC is being compared to something that

|
||
|

: 1. the MIPS R4000 is hardly the fastest processor made by MIPS. The

|

: want to compare apples to apples, use a new Indy with a MIPS R4600
|
||
: processor at 166 Mhz. It blows the doors off Pentium 90. Would you
|
||
: like to send your code to me so I can run it on a new SGI machine?
|

|

|

: 2. SGI Indy does not cost ~3 times more than a top of the line DELL.
|

: Let's look at the numbers, shall we:
|

|

: Dell XPS 90, 16Meg ram, 17" monitor, #9 graphics card,
|
||
: CD Rom Drive, 1G IDE disk, ethernet card, 3 year warranty.
|
||
: Price: ~$4400
|
||
|

: SGI Indy, 16 Meg Ram, 17" monitor, accelerated graphics
|

: 1G FAST SCSI Drive, ethernet, CCD camera, 3 year warranty.
|

: Price: ~$6500
|

|

: You should note the the Indy has a MIPS R4600 processor, which is

|

: higher throughput and lower price/performance.
|
||
|
||
OK we bought an SCI Indy with the R4000 100MHz and 16 Mb RAM...
|
||
We bought it in oktober '93 so its already "old" however *IT SUCKS*
|
||
It has for instance no external cache.... here is the hinv output:

logging in on console takes over 1 minute...We use insightII from BIOSYM,
|

actually we bought the software (insightII and ...) from BIOSYM, with it
|

came the machine for a price of Dfl 20.000,= (US$ 12000,=).
|
||
the system has no c-compiler and I can go on like this for a minute.
|
||
|
||
Running insightII is the biggest dissaster happening to you...
|
||
|
||
Ok the demo which was installed was alright, but this machine is in practice
|
||
a failure....

He your email adress is not valid! Ever tried to set up some intelligent
|

networking (e.g. sub netting) from within the sysadmin X program on a Indy?
|
||
it doesn't work. So I had to use a normal xterm and vi and some tough hacking
|

in those over 500 lines long corrupted scripts (My Linux experience helped
|

me out) to get it going...IRIX is certainly not my favorit UNIX...

|

Date: Fri, 23 Sep 1994 02:43:23 GMT
|
||
|
||
I have two problems/questions:
|
||
First, the easy (or short) one. When I run top right after a cold reboot, it
|
||
shows most of my main memory is being used (less than 600K) free. I just
|
||
recompiled my kernel, I now have version 1.1.50. Also, I don't know if
|
||
this is related, but I was looking in my /var/adm/messages file, and the
|
||
kernel had reported several times that bdflush wasn't running. What is
|
||
bdflush? Any ideas as to what's causing this? (my system info is at the
|
||
end of this letter).
|
||
|
||
Second, I have a major sound problem. I've got an SB16, and I'm using version
|
||
2.9 patch2 of the sound driver. Anyway, whenever I try to play anything that
|
||
has 16-bit sound, my computer either locks up, reboots, or the kernel panics.
|
||
This happens for things like DOOM and when I try to play MODs at 16-bits with
|
||
s3mod. Here is the debugging output from the latest panic (this is after
|
||
running X, compiling a few programs, and playing a few MODs at 8-bits):

|

Turtle Beach Rio waveblaster daughterboard

|
||
Zoom faxmodem installed on COM2 14.4 kbps
|
||
MS mouse 2.0 on COM1
|
||
|
||
I have no problems with 16-bit sound under DOS, BTW.
|
||
|
||
Also, does anyone out there know of a MIDI player for linux that'll use
|
||
the Rio daughterboard?

I found different results. A few months ago, when I was playing with

an mpeg decoder, I regularly saw 10-15% faster results with 2.4.0p.

YMMV.
