Subject: Save my 486... Linux and HDD controller board
Date: Sun, 29 Aug 1999 22:59:18 +0800
I have got myself an old 486 with a 243Mb Hard drive... a great tool for
trying out Linux networking...
I created a boot disk out of the disk image provided by my Mandrake RH
6.0 CDRom... When the 486 is booted with the boot disk, the partition
check always give a bunch of error messages:
Partition Check:
hda/hda: status error: status=0x01 {error}
hda/hda: status error: status=0x04 {DiskStatuserror}
Drive not ready for command
The hard drive is connected to the 486 thru a HDD controller. The
problem seems to be stemed from the controller board. Any idea how I
would solve the problem here?
After several reboots, I decided to simply ignore the error messages...
and I finally managed to get the installation done... although after a
number of unsuccessful attempts. I could reach the logon screen after
the installation... but when I entered my username, an error message pop
up saying something like ld... (don't quite remember)... and I was
unable to enter my password. After several trials, another message pop
up staying that the system was going to stay frozen for 5 minutes...

First, sorry for ringing in late, but I just ran across the question today,
and just registered today.
Any computer System Security, of a serious - professional nature (in my
opinion, this leaves MS's security out altogether) relies completely on the
central processor's use of the 'Supervisor Mode', its implementation, and
the 'Supervisor Mode Instruction Set'. I am not familiar with INTEL's
implementation, but I am familiar with the IBM System/3x0 use of Supervisor
Mode.
If the Supervisor Mode Instruction Set is set up logically and completely,
as with the IBM System/3x0 MainFrames, the Operating System source Code can
be published and given out with the Operating System (as it was until the
1990s), and it will make no difference on the security of the System.
The premise being that only programs from an Authorized Library can switch
from Program Mode to Supervisor Mode. All I/O, Setting Storage Protection
Keys, and modifying Interrupt Vectors is restricted to programs running in
Supervisor Mode. Simply Stated, You can Know the System like the back of
your hand, but if you can't execute any I/O, you are not a Security Threat.
Of course the actual implementation of this is quite elaborate and prone to
Logic Errors (Bugs), and there is the Physical Security part of the
equation, in that, when you (or anyone else) "Boots" the System, the
"Booted" program is automatically in Supervisor.
I hope this gives you another point of view about System Security.

Nope. You need to get a *real*, *hardware* modem. Any commonly
available external, serial, RS232 modem will work. There are a
*couple* a real PCI modems, but they are rare, hard to get, and
expensive. Some of the older ISA internal modems work. Winmodems
only work under MS-Windows and under NO OTHER OPERATING SYSTEM,
including Linux, MS-DOS, etc.

on my MBR sits OS/2 bootmanager which loads lilo.
this part works fine. LILO loads because i get LI_.
Also, before my partition number got changed, the same
installation worked perfectly. The problem is that since
sda7 ( / ) become sda6 &
sda6 ( /boot ) become sda5
and nothing else was changed, LILO stopped working though I
changed nothing except the corresponding lines in lilo.conf
and
fstab and rerunning lilo.
Gabriel,
PS. thank you for the rdev insight, in moments like these
I'd believe
in voodoo. So I tried it just in case.
