Hi Jim;
|
||
</strong></p>
|
||
|
||
<p><strong>
|
||
To let you in on what I have done:-
|
||
</strong></p>
|
||
|
||
<p><strong>
|
||
I have an AMD 586/133 processor, 24M RAM, 2 x HDD (2.5G and 635M)
|
||
run Linux off the 635M and boot in with floppy using LILO.
|
||
</strong></p>
|
||
|
||
<p><strong>
|
||
Win95 is resident on the main 2.5G which is formatted as C: and D:,
|
||
</strong></p>
|
||
|
||
<p><strong>
|
||
The problem occurrs any time that Win is run from a restart, be it a
|
||
warm boot (Ctrl-Alt-Del), full power off, or reset button.
|
||
</strong></p>
|
||
|
||
<p><strong>
|
||
Its as if its trying to ascertain what is on the second drive and
|
||
can't. It finally allocates it as a 2nd CDRom drive. You can't
|
||
access it or get any more info from it.
|
||
</strong></p>
|
||
|
||
<p><strong>
|
||
I've tried re-installing the OP/SYS and have tried it with Win95 on
|
||
its own but the same thing happens.
|
||

of whether Linux has been installed or not.

What sort of controller are you using? Is it IDE? SCSI?
|
||
If it is IDE you'll want to double-check the settings
|
||
with regards to "master/slave/standalone." If you have
|
||
two IDE channels (pretty common these days) you might
|
||
try putting the second drive on its own cable, on the
|
||
other controller channel.

<BLOCKQUOTE>
|
||
If this is a SCSI controller, double and triple check the
|
||
ID's, any pin settings and options on the drives and
|
||
the termination settings/resistor packs on the drives and
|
||
on the controller, and any settings on the controller or
|
||
accessible via its "setup program" (firmware or software).

|

In either case, try replacing the cables.

|

The 635Mb drive is pretty small these days. You might
|
||
consider setting it aside and springing for an extra
|
||
2 or 4 Gb drive.

Hi,

|

|

<strong><p><font color="navy"><em>
|
||
I'm sorry if you've had this one before and I don't want to waste
|
||
your time but I've put Linux on for the first time and have no
|
||
previous experience. I really put it on because I would like to
|
||
learn something new. Anyway the problem is that when I boot to Win95
|
||
in which I have most of my programs, the first time that I try to do
|
||
anything that requires reading of the hard-drives the computer stops
|
||
responding for a considerable period. Some times up to 10 mins. Is
|
||
this normal or can I bypass this problem with some sort of
|
||
configuration. It's not too big a problem because it only happens
|
||
once during any session but it is a pain in the @$#%^$. Your help
|
||
would be greatly appreciated.

If I understand you correctly you're saying that,
|
||
since you installed Linux when you reboot into Win '95
|
||
your first subsequent access of the hard drive causes
|
||
a hestitation of several minutes.
|

|

Is that a proper understanding?
|
||
</blockquote>
|
||
|
||
<BLOCKQUOTE>
|
||
If so I'd just simply be baffled.
|
||
</blockquote>
|
||
|
||
<BLOCKQUOTE>
|
||
Does that only happen after a "vulcan PC pinch"
|
||
warm boot (Ctrl-Alt-Del), or after a hard boot (reset
|
||
button on the case), or does it happen after a
|
||
full power cycle (wait about 15 to 30 seconds between
|
||
power off and powering back up)?
|
||
</blockquote>
|
||
|
||
<BLOCKQUOTE>
|
||
Does this happen only once? Or does it happen periodically?
|
||
</blockquote>
|
||
|
||
<BLOCKQUOTE>
|
||
I've seen some devices (ether cards mostly) that could
|
||
"stay confused" through a hard boot. However, I can't
|
||
imagine anything that Linux would do to your hardware
|
||
that would cause this behaviour.
|
||

|

|
||
<BLOCKQUOTE>
|
||
In cases like this (where something inexplicable is
|
||
going on and the secondary OS <EM>seems</EM> to be involved)
|
||
I suggest removing the new software (Linux) and testing
|
||
again. If that doesn't work try backing up all of your
|
||
data and doing an IPL (initial program load --- i.e. a
|
||
complete re-installation of your system software).
|
||
</blockquote>
|

|
||
<BLOCKQUOTE>
|
||
Please note that Linux can run off of removable drives
|
||
and can be loaded from a DOS prompt (Win '95 "Safe mode").
|
||
So, once you have your system behaving properly again you
|
||
can explore alternative ways to access Linux that are even
|
||
less likely to affect the rest of your system.

|
||
If you're really motivated, and you can isolate it to a
|
||
particular module, driver, or application <EM>under</EM> Linux that
|
||
is causing the problem, it will be very helpful. If you're
|
||
<EM>really</EM> motivated, and more of a programmer than I, you
|
||
might even track down and fix the bug --- since that's what
|
||
the sources are for. At least you might try building a
|
||
couple of different kernels (try stripping out everything
|
||
except the disk/controller driver that applies to the
|
||
controller on which you've installed your root filesystem --
|
||
leave out the the sound, and ether drivers, and boot up
|
||
into single-user mode --- don't start X or xdm and just
|
||
reboot back If the problem never occurs in this configuration
|
||
then you can keep adding things back until the problem recurs
|
||
--- or you've got Linux running the way you want).
