Modify conf.modules for your CDROM writer, my CDROM is located at /dev/hdc
Here is my conf.modules
alias scd0 sr_mod
alias scsi_hostadapter ide-scsi
options ide-cd ignore=hdc
# cp /etc/rc.d/rc.local /etc/rc.d/rc.local.bak

Put this at the end of the rc.local
# load ide-scsi module
insmod ide-scsi
# cp /etc/lilo.conf /etc/lilo.conf.bak
# vi /etc/lilo.conf
put the append statement for /etc/lilo.conf your cdrom
'append="hdX=ide-scsi"' and run lilo.
Here is /etc/lilo.conf, my CDROM is located at /dev/hdc
boot=/dev/fd0

Now relink the /dev/cdrom to your scsi emulation of your cdwriter
# mv /dev/cdrom /dev/cdrom.bak
# ln -s /dev/scd0 /dev/cdrom
Reboot. (I don't know how to restart with new conf.modules and rc.local

Run dmesg to see if your scsi emulation is working after the reboot

What you are proposing would work.
A simple solution would be to just add your new disk ...keep your operating
systems as they are...and have each make use of the new drive
...however...i would be a bit uncomfortable having two operating systems
split up over two drives.
I personally would let the kids have the ENTIRE 4.3 gig disk for Windows...
then you take the ENTIRE 10gig disk for Linux.
This way the kids can do whatever they want PLUS
Didn't you REALLY want to do a totally fresh Linux installation and correct
all those little things you wanted to improve upon?

Subject: Lilo Problem
Date: Thu, 13 Jul 2000 02:43:48 GMT
Obviously I did something wrong when I recently
loaded Linux Mandrake. I didn't get a lilo
prompt. Using my boot disk I reran lilo only to
get an error message reading: "warning: device
0x030c exceeds 1024 cylinder limit.
"geo_comp_addr: Cylinder number is too big
(2203>1023)"
I know lilo has to go before the 1024 limit and
for the life of me I don't know how I messed up
the install. Can lilo be installed? Or do I
have to do a full re-install?
Thanks in advance,
Dhill

Subject: Help! Cron and Samba / Cron and missing directories?
Date: Thu, 13 Jul 2000 09:42:26 +1000
Hi,
I've got 2 problems related:
PROBLEM 1
~~~~~~~~~~
I'm trying like crazy to get samba to restart every day at 4:30am.
I have tried the following:
a) - typing in crontab -e, and adding the line 30 4 * * * samba restart
(while being user root)
b) editing the file /etc/crontab and adding the line 30 04 * * * samba
restart (again as root)
c) - typing in crontab -e and adding the line 32 4 * * *
/etc/rc.d/init.d/samba restart
I'm finding that the next morning, I have quite a few mail for 'root'. These
consist of
a lot of messages saying "not a directory :/etc/cron.hourly"
one that says "not a directory :/cetc/cron.daily"
and another saying /etc/rc.d/init.d/samba no such file.
I've looked under the /etc/rc.d/init.d/ directory, and can see a file called
SMB but not SAMBA.
SMB appears to act the same as samba, but I usually type in "SAMBA" at the
prompt when I'm
as root - and all works fine. Should I be typing in something else?
PROBLEM 2
~~~~~~~~~~
These nasty little messages filling up my mail box saying 'not a directory'
/etc/cron.hourly
I have got a directory there. I can go cd /etc/cron.hourly and I move to
that directory! Does
anyone have a clue whats happening here too? Ta

Hi. I have a Linux question.
I'm running SCO Foxpro 2.6 for Unix on Linux. Works ok, but with a problem.
The date/time is 4 to 5 hours fast. Depending on the GMT offset of the
machine. I can write date/time functions to rollback this offset. But is
there an environment variable or something I could test to determine the
machine's Greenwich Meridan TIme offset?

Both exist; it is more likely that someone would find, at random, an
Alpha Multia, because when they discontinued them, Digital sold
several thousand off, and their use has been quite widespread in the
Linux community.

There most definitely _are_ "boxed sets" that run on Alpha processors.
I bought Red Hat 4.1 for Alpha several years back, and there have
continued to be RHAT releases for Alpha. Mandrake and SuSE have been
more recent "adopters" of the Alpha platform. And I run Debian on my
PW433e.

I can tell you that Red Hat 6.2 does indeed run into the 1024 cylinder
problem. I should know since I tried to install it and only got "LI" to
come up, which means there's a geometry mismatch problem. For more
information on this problem visit the LILO Mini HowTo Documentation
available at http://www.linuxdoc.org/HOWTO/mini/LILO.html

Subject: Using NT bootload to boot to linux
Date: Wed, 12 Jul 2000 23:43:47 -0400
I know this has been asked alot of time ... however, it doesn't work out in
my situation , can't figure out what's wrong with it .. please help.
My Redhat 6.2 was installed without no lilo.conf in the /etc directory
(because I choose not to have lilo installed, I'll make it later)
Linux was installed on the 1st partition of the 2nd HD , HDB1
After RH was installed, I use the command rdev /boot/vmlinuz /dev/hdb1
(just to make sure)
and then created a lino.conf in /etc like this
===================================
boot = /dev/hdb1
compact
install = /boot/boot.b
map = /boot/map
image = /boot/vmlinuz
label = linux
root = /dev/hdb1
===============================
and ran /sbin/lilo after that
After that , I do the normal steps like
dd if=/dev/hdb1 of=/bootsect.lnx bs=512 count=1
copy file that bootsect.lnx to my NT's C drive
edit the boot.ini C:\BOOTSECT.LNX="LINUX"
.... Everything is done like the helpfile said
However during Nt loades, I choose Linux ... the screen went blank with
the cursor blinking .... no disk activity whatsoever ...
What's going on with that ?
I've done this before with Caldera 2.3 so I am pretty sure the bootsect.lnx
part is correct ... Something's wrong with the lilo or something ??
Thanks for all input.

Most of the device drivers are compiled across several versions. All the
sub-releases 2.2.* or 2.4.* use the same source files. In some cases (sound
drivers), the original 2.2 source files are used in both 2.2 and 2.4. Driver
updates (very few of them) are manually patched into the common source.
Everything elses are from standard releases.

If I understand your post correctly, you have a "delegated" domain name
(a.b.com) under your ISP's domain space (b.com). If this is the case, you
will need to setup a name sever at your end that contains the Start of
Authority (SOA), Name server records (NS), Address records (A) and Mail
Exchanger (MX) records for your delegated domain. Otherwise no one will be
able to send e-mail to you at your delegated domain name or even access your
WEB site.
The DNS abd BIND book discusses this subject in detail and has some execent
examples.
Also, I would verify that your ISP has porperly "delegated" your domain name
to your IP address. You can use dig ot nslookup to verify.

Change "samba" to "smb" so that the line looks like this
"/etc/rc.d/init.d/smb restart" without quotes.
