Greetings:
I'm trying to set up a machine for a friend, but I've hit some snags:
1. I found a Diamond SupraExpress 33.6 modem (SUP1690) but I have no
documentation for it and can't figure out how to set the jumpers. I also
need a working init string for it to use in a DIP script.
2. I was able to set up X and get it working properly, one time.
Since then, if I so much as move the mouse (whether in X or not), it
knocks the keyboard off-line and the entire system freezes. I've tried
using a couple different mice (a Dell 2-button and a new Logitec
Mouseman 3-button, both PS/2 style), but the problem persists.
The system is:
486/100 w. 16 megs RAM
Red Hat 5.2 custom install, stock kernel
Any & all advice would be vastly appreciated !

If you have enough ram you won't need any swap.

Subject: Linux on a Cubix
Date: Tue, 18 May 1999 14:49:33 -0400
Hi All,
A client just donated a couple of Cubix ERS/FT II multi-CPU systems
to us. They were being used in a classic configuration with a single
BC5090 (90 MHz Pentium) control board running NetWare as a server and a
set of QL4222 (dual 486) workstation boards which remote boot from the
NetWare server.
These systems were being used as a NetWare ACS dial-in system, but I
was wondering if I could use it in a more useful setting - say, as a
cluster of Linux systems? Anyone tried this before, or know how to make
it work under Linux? I expect that getting Linux to load on the BC
system will not ne too difficult, but does anyone know how to make the
QL workstation systems remote boot from a running Linux system on the
BC?
Thanks,
Roy

It depends, but generally yes, you will need to configure whatever machine
connects to the ISP to use DHCP (or more precisely the client program DHCPCD).
You should make sure the clients (and server if you use a firewall) all use IP
addresses that are reserved for private use (10.x.x.x, 172.16.x.x,
192.168.x.x).
Note there are some ISP's out there that state they don't allow a computer
providing internet service for a lan (you are supposed to buy separate cable
modem service for each PC). I've seen some reports that they will refuse to
deal with you if your computer has a lilo prompt. Hopefully, you have a more
enlighted ISP.

I don't have cable service, but I believe the cable installer just plugs the
cable box into your NIC (basically the original hub does not share any wires
with the NIC/cable modem),

Yes, unless you get a fixed set of IP numbers.

It might be less disruptive to use a firewall (that way the server is the same
config as before except you set up routing through the firewall). It is also
more secure, especially if you don't allow access without passwords from the
firewall to the client machines (rlogin, nfs, etc.), and use different
passwords on the firewall.

I have experience only with isa cards (the cyclades ones, in
particular). if you have some spare isa slots, I have some 8-port
rs232 cards that I could unload.
its almost a shame to waste a 'valuable' pci slot for something as
mundane as low-speed serial.

I have been picking up Matrox G100 4Mb cards for about $18. These are
OEM cards (the retail G100 is 8Mb only, I think). I'm quite happy with
them for "standard" display (i.e. 2D). These were AGP cards, but they
make PCI versions too....
I've used GX2 based S3 cards with success also (mentioned in another post).
I'm not sure about 1600x1200 on these cards (very likely supported, but
at what refresh?), but I'm sure 1280x1024 is fine (at least 72Hz I imagine).

Well, truth be told, colors look ok, but other issues (Displaced screen,
core dumping) have forced me to use Xawtv, which for the most part works
fine, and looks great.
There still isn't any sound. I've gone over the board with a penlight
and a magnifying glass, and still can't identify the sound chip. Any
idea what it is?
Are we the only ones who can't get sound with their avermedia? (mine is
a standard TVPhone, not a TVphone 98).
Best regards,
Dan.

What's the secret to getting a DDS-3 DAT drive to work with linux?
I've tried reading/writing tapes with Redhat 5.2 and Redhat 6.0
using an HP and a Seagate drive without success.
When I try to read/write tapes, I get:
tape read error: Input/output error
I've compiled SCSI tape support into the kernel (tried both 2.0.36 and
2.2.9) and made sure the device files (/dev/nst0 /dev/st0) exist.
Anyone have any suggestions?

I need to upgrade glibc/libc, the files in these (rpm) packages
obviously conflict with the existing ones (in my RH5.1). I'm all worried about
uninstalling the existing ones, because I don't understand how then Linux is
going to install new ones without any working glibc/libc. Please, help me
understand how to do that if you can.
thank you.

Hi,
I have a Traxdata drive and it used to work fine but seems to have
developed a _very_ annoying habit of creating coasters. It started of fine
but after about 6 months it became unreliable. I know of another person who
has said the same thing, but another person I know has had absolutly no
problem with it.
I know that probably doesn't help much but it's just the experience I've
had with the traxdata drive (which is a rebadged Yamaha drive).

Subject: Help: Winnt+Win95B+Linux triple boot!!!
Date: Tue, 18 May 1999 19:44:40 GMT
Hi,
I have an AMD K6-2 266 MHz w/8.4GB WD Caviar drive (C/H/S
1027/255/63). I partitioned it like this using Linux fdisk:
Type Partition Start Cyl. End Cyl.
Size
Prim. /dev/hda1 1 127 996MB
Prim. /dev/hda2 128 256 1000MB
Ext. /dev/hda3 257 1009 5906MB
---Log. /dev/hda5 257 511 2000MB
---Log. /dev/hda6 512 768 2000MB
---Log. /dev/hda7 769 786 136MB
---Log. /dev/hda8 787 1009 1750MB
Prim. /dev/hda4 1010 1027 144MB
The pupose of the partitions are:
/dev/hda1(C: in DOS) Windows NT operating system and related files
/dev/hda2(F: in DOS) Windows 95B operating system and related files
/dev/hda5(D: in DOS) Common program files between Nt and 95B
/dev/hda6(E: in DOS) Common program files between Nt and 95B
/dev/hda7 Linux swap
/dev/hda8 Linux /usr mount point
/dev/hda4 Linux root
I started off installing Win95 first on F: drive, then Windows NT 4.0
on C:; I tested them for a while. Then I installed Linux Redhat 5.0,
and added the linux boot code to NT partition C: (/dev/hda1), and
added the Linux entry to the NT bootloader menu. It booted Linux
properly , but after that when I tried to boot Win95, it
would not boot any longer, it hung saying there were a bunch of
corrupt files. WiNT had no problem, however. So I reinstalled Win95
on F: (/dev/hda2), and the next time I tried to boot Linux, Linux said
its file system was not proper, and doing a check, it dropped to a
panic mode, and there were a huge number of repairs it went through
when I ran e2fsck (Note: e2fsck would not run with the -a 'automatic
repair' option, so I was interactively going through this) Finally I
gave up, and reinstalled Linux, and again WIn95 was clobbered. This
went on for several iterations.
Then I ran Disk Druid instead of fdisk, and it seemed to think my
partition table was corrupt, and exited abnormally, wiping out the
entire partition table!! SO I started from scratch, repartitioned the
hard drive, This time I installed Linux first - I thought that would
make a difference. Linux was on drive /dev/hda4 again, and this time
I asked LILO to write the MBR, knowing that Win95 will wipe it out
when I install it. So then I installed Win95B and then Winnt4.0.
After that I tried booting linux using a floppy to start it, and it
said the root partition was not unmounted properly, therefore a check
was enforced, and again it dropped into a panic mode.
Any suggestions? Ideas?!
I saw several articles on the web about triple booting, so I know this
has been done before - but why is it failing when I try ?
