Hi,
I messed with /etc/fstab and instead of /dev/sda1 I typed /dev/hda1. Now
at boot time the system is trying to mount /dev/hda1 that doesn't exist.
After typing the root password I am logged in a recovery mode where the
root filesystem is mounted as readonly and I cannot edit /etc/fstab. How
can I change the mode to rw?
Thanks in advance.

It started some time back with this error at the login prompt.
manx login: SCSI0 Tagged Queing now active for Target 2.
Recently the machine would randomly lock up which I thought initially was
the jdk in Netscape. Then I got ..
SCSI host0 abort (pid 368471) timed out.
Resetting Buslogic BT958 due to target1
SCSI bus is being reset for host 0 channel 0
Now after a couple of false starts and aborted fsck with...
Kernel Panic: SCSI_free: Trying to free unused memory
in Interrupt handler - not syncing.
and so the machine now doesn't boot and the primary partition is probably
hosed due to all kinds of bad inodes by now.
Can some one shed some light on this and help me diagnosed this to
determine if this has an origin in bad hardware or is it a case of
corrupted software.
Also any pointers to SCSI diagnostic utilities to test/troubleshoot the
SCSI bus will also be greatly appreciated.

$ man mount
remount
Attempt to remount an already-mounted file
system. This is commonly used to change the
mount flags for a file system, especially to
make a readonly file system writeable.
would be one way of trying it. If this filesystem is not
"critical" you could simply let the machine boot, fail the
mount and carry on into multiuser mode. Then as root, fix
fstab and mount the filesystem by hand.
Alternatively, boot the system from some recovery medium,
and mount the root fs somewhere like /mnt and edit fstab
that way.

Date: Fri, 04 Aug 2000 21:05:46 GMT
hey there,
i'm running a bare bones linux system on a REALLY OLD piece of
hardware. it's some kind of a 486 with a 100mhz processor and 8mb of
RAM. occasionally i get an error message "Segmentation fault" that
crashes whatever application i'm running. it's not really frequent, but
can be a pain with a program that takes a long time to run, like an
installer. does anybody know what a "segmentation fault" is? what piece
of hardware is causing this?

This doesn't look healthy but I'm not familiar with Pentium-based
boards. Do the kernel configuration file selections for system and
block device selections match your motherboard's memory and disk I/O
chipset?

I thought the later kernel (shipped with RH 6.2) did support Lanstreamer.
But I've gotten TR cards to work without specifying io and irq... did you
try that? I don't know which of the TR cards was inside, however.

Use an early version of Slackware. Slackware 7.1 wouldn't
install my on 486DX33 with 8Mb, I had to install Linux by
putting the drive into another more modern computer with
much more RAM. Now runs ok on the 486.
Try the boot and root disks for Slackware 3.5, before downloading
the rest of the packages. If that doesn't work, you need to
get more RAM or use the above hack.

Hal,
Yes , not being able to access certain web sites was the only symptom that
I saw.
My understanding, is as you say, that the MTU must not exceed that of the
lowest setting
along the path to the destination, which in this case was a website.
So far, I haven't had any problems downloading, but then I haven't downloaded
much lately.

Is this an ISA modem or a PCI modem?
For PCI exec the command "lspci -v | less" as root. The output should
include something like this:
00:12.0 Serial controller: US Robotics/3Com 56K Fax Modem Model 5610 (rev
01) (prog-if 02 [16550])
Subsystem: US Robotics/3Com USR 56k Internal Voice Modem (Model
2976)
Flags: medium devsel, IRQ 14
I/O ports at ec00
Capabilities: [dc] Power Management version 2
Then add a line like this:
setserial -b /dev/ttyS0 port 0xec00 auto_irq autoconfig
to the appropriate "rc" script ("rc.serial" on my system). The two
things which you need to change in the line are the number of the tty and
the port address, the tty depends on which com port it is using (e.g. for
COM1 use ttyS0) and the port is the "I/O port at" from lspci (in my case:
ec00). Remember, the I/O port address may change if you install more
hardware.
AND, just how do you determine that the modem is connected to COM1? I do
not know, but if it is the only PCI serial device that is probably where
it will end up. Actually, it appears that you can chose, but I would
suspect that it would be better to use one that was not already in use.
If you don't have "lspci" you can exec the command: "cat /proc/pci" and
your output should include something like this:
Bus 0, device 18, function 0:
Serial controller: Unknown vendor Unknown device (rev 1).
Vendor id=12b9. Device id=1008.
Medium devsel. IRQ 14.
I/O at 0xec00 [0xec01].
Which shows the same I/O address.
These are generic instructions for PCI modems. They worked for me!
If you have ISA, you will have to ask someone else.

did you read the lilo howto?
LI The first stage boot loader was able to load the
second stage boot loader, but has failed to execute
it. This can either be caused by a geometry mismatch
or by moving /boot/boot.b without running the map
installer.
Are you doing something weird with the disk?
