Go into the Adaptec card's BIOS (usually ctrl-A), and tell it not to scan
the bus, and not to try and install the boot BIOS.

The ECC works at a hardware level, not in conjunction with the OS. The
question is "does your motherboard's memory controller support it, and is
the support enabled in the BIOS?"

Subject: SCSI tape problem
Date: 7 Dec 2000 22:03:10 GMT
Reply-To: [EMAIL PROTECTED]
Hello,
I have 2 questions/problems with an Exabyte 8505XL 8mm tape drive. It is
mounted internally, and is 1 of 7 devices (full load) on an Adaptec 2940U
All devices work fully in Win98 and Win2000. I leave the power turned
off the tape drive and 2 external devices except when I want to use them.
I recently added the 7th device, an IBM 9GB hard drive (internal) and
installed SuSE V7.0 on it, kernel 2.2.16. Works very well, except...!!
I expected to be able to use tar with the tape drive to transport large
files to and from a Sun machine.
--##--
1. The tape drive IS visible during the early stage of boot when the
2940 is found.
In Linux, the tape drive is NOT present as seen using the SCSI info in
"kdm" (I think) or even using "cat /proc/scsi/scsi"
If I boot the machine with _either_ (or both) of the 2 external devices
turned on, (a scanner and a CD burner) the tape is recognized when I
boot into Linux and works OK with "mt /dev/st0 status" and tar.
Any ideas or suggestions on what the heck I can do to get normal SCSI
function without having to remember to turn on an unneeded device???
--##--
2. After the tape is recognized by Linux, I can create and extract tape
without a wimper, AND read & extract the same tape on the Solaris box.
However, I can't extract (same version of gnu tar on both boxes) from a
tape made on the Solaris box to my Linux machine.
mt /dev/st0 status shows "block size 1024" for a Solaris tape on the
Linux box, and tar tvf /dev/st0 bombs out with an I/O error.
I found that "mt" has additional functions in Linux (more than Solaris
2.7) which I learned about on the Exabyte web site.
I learned that if I manually set the Linux block size to "variable"
mode, (ie 0), then it can read/extract Solaris tapes.
mt /dev/st0 setblk 0
So, can I set a parameter to set this, (change default) during boot?
Thanks,
David

Lilo must be on a bootable partition, Linux itself can be anywhere.
The Lilo docs/mini HowTo explains this. Alternatively loadlin can
be used or a floppy (bootable of course).

While this is strictly speaking correct, it would be interesting to have
the memory controller report errors (corrected or detected but not
corrected) to the OS. This could signal a faulty memory chip, or at the
least warn the administrator or user that the system is becoming
unreliable... Why isn't there support to read these errors?

Salut,
I run redHat 6.2 with an inboard SCSI card (adaptec 160M). 2 disks are
connected on this card and linux boot on one of them (sda). I add
another SCSI card (IDE adaptec 160M) to connect external devices (zip
250 and Dat).

My chain is fine AFAIK. I have loaded DOS 6.22, Win95, and NT 4.0 and
all work fine.

Yes, that's the question. Is that adaptek SCSI device bootable. I am unable to boot at
start up from
the RH 6.2 CD-ROM regardless of how I set the device choices. I can boot up on another
machine with
an IDE drive.
If it requires replacing this old SCSI adapter, what's a good replacement. I have two
SCSI-2 devices
on my machine. How does on go about replacing it? I would imagine that I would install
a new card,
then remove the old card and moving the necessary SCSI device cables to the new card.

This is an excellent question!
I have seen such reporting on Sun and SGI machines.
I got a parity error on both types of machine.
So, to those who say memory errors never happen... you better look out.

Suppose the memory that holds the kernel segment that responds to memory
errors goes bad? ("Kernel panic: Error in error handler!") When you
set up a system to report faults, it is best to make sure the faults
being detected can't bugger the reporting system--which means in this
case, putting the ECC error handler in ROM.
I've heard of ECC controllers being able to store failure info in the
motherboard's NVRAM, which the OS could certainly read. Don't know the
specifics though.

Ok, I got a related question .... how come that the additional ram
chip (going from 8 to 9 in the average module) pretty well doubles the
price tag (this is a wild guess but I certainly remember having to
pick up my lower jaw off the floor when I was asking my dealer for ram
prices on ECC nodules)

My question: What's the best mobo to use for building a new Linux system? I
am planning an Athlon 900 Mhz Socket A, so obviously my question relates to
mb's that support that chip. I plan to use Mandrake 7.2 as my distro (see
below) and an IBM Deskstar 75GXP HD.
I've been bouncing back and forth between the ABIT KT7-RAID, ASUS A7V, and
Microstar KT7-Pro2A. As you can see from my choices, I'm looking to run the
HD at ATA100. Although all three boards are also good to OC, I'm probably
not going to do that, at least at first.
I've heard than Mandrake 7.2 supports the Promise ATA-100 controller out of
the box, which makes the Asus board attractive, but I've also read about a
ton of bios related problems with that board (of course, I am sure just as
many people hae trouble with the others too).
Any thoughts...success stores...warnings?

I want to build or purchase (will probably end up building) a system for

I am also thinking of bending my budget and going for a Pentium II or maybe
even an AMD Duron. My main question is:
What type of processor and motherboard would you recommend that I use to get
the best bang for my buck? And are there any online retailers that still
sell parts this old. Remember, this is only going to be used so I can learn
about Unix/Linux/BSD, so I don't need anything better than the lowest end
Duron, and I don't even need that. Thanks for your help everybody!

Because the capability to do this is totally broken in just about every
x86 chipset that claims to support ECC.
A friend was working on this a while back but basically abandoned the
project when he realized how badly the support was broken.
