Description Robin Walker 2001-06-06 01:08:35 UTC

Description of Problem:

I upgraded from RH 6.0 to RH 7.1 and chose all the default options, installing the LILO boot record on the MBR, the boot image on what I 
assume to be the boot partition which in my case was /dev/hda7 (the only choice available), and creating a boot disk.  When rebooting, 
immediately after BIOS installation where LILO normally kicks off, the following two lines are displayed:

Error 0x40
boot: linux

These two lines are repeated every 4 seconds, ad infinitum.

I repeated the upgrade with the same results.  I am, however, able to boot into the system using the boot diskette that was created during the 
upgrade process.

How Reproducible:

Try upgrading from 6.0 to 7.1 on similar hardware.  My hardware is an AMD K6-2 450mhz based system.

Steps to Reproduce:
1. Acquire similar hardware and install RH 6.0
2. Upgrade to RH 7.1, using default choices
3. Reboot

Actual Results:


Expected Results:


Additional Information:

Comment 1 Doug Ledford 2001-06-06 15:10:32 UTC

Boot into the system using the boot disk you made, then run the lilo command and
seeif it returns any errors.  If not, that *may* solve your problem (I'm not
sure what the BIOS error code 0x40 means, it could mean a failed read which
would indicate a drive that has a bad sector and re-running lilo to rewrite that
sector might make it work).

Comment 2 Robin Walker 2001-06-08 00:38:29 UTC

Unfortunately, this did not solve the problem.  I booted with the boot diskette and ran the lilo command which had the following output:

Added linux *

Removing the diskette and rebooting produced the same results as initially described.

Comment 3 Michael Schwendt 2001-06-15 19:19:02 UTC

From LILO's docs:

0x40   "Seek failure". This might be a media problem. Try booting again.

Comment 4 Robin Walker 2001-06-21 00:32:35 UTC

I tried booting again.  In fact I've tried rebooting several times.  The same "0x40" error message appears every time.  I also tried performing the upgrade 
again.

Comment 5 Jeremy Katz 2002-06-04 06:31:46 UTC

It sounds like a failure on the first sector of the drive for me... have you
continued to have problems with newer releases?

Comment 6 Jeremy Katz 2002-06-29 21:48:51 UTC

Closing due to inactivity.  If you have further information, please reopen this bug.
