Re: donut is dead, long live the donut

 I've tried reinstalling both LILO and the Debian MBR.  Neither
 'install-mbr' nor rerunning 'liloconfig' seems to have had an effect.
i don't know, what liloconfig is for, but does it automatically run lilo?
the invocation of /sbin/lilo does the actual installation of the
boot sector/mbr ...

Actually, it doesn't.  (And yes, I have run both LILO and installed
the Debian MBR directly; that had no effect.)  The default setup is to 
install LILO on the root partition, rather than in the MBR.  A short
specialized MBR is installed instead.  Just about all of the
functionality it has is to offer a choice of partitions to boot from,
with a default of the first active partition.  It doesn't even have
much of an interface; for me, it would display 1FA: if tweaked.

But this turns out not to have been a problem.  After messing with
things some more and finally creating a floppy with GRUB on it, I
discovered that the system would just freeze if I tried to touch the
hard drive before a Linux kernel booted.  I traced this back to a BIOS
setting: my system has a known buggy CMD640 IDE interface, and I had
disabled the write prefetch option in the BIOS.  The system *really* 
didn't like this, apparently, I re-enabled it and everything is
more-or-less happy now.

donut is dead, long live the donut

2000-05-11 Thread David Z. Maze
I have a reasonably current woody system, named donut.  In a fit of
bravery mixed with stupidity, I was playing with 'hdparm' to try to
improve disk performance.  I must have broken something (and caused
MASSIVE FILESYSTEM CORRUPTION; hdparm(8) seems overly paranoid),
because I wound up having to reboot and things massively failing.

The problem: the BIOS looks at the hard disk, proclaims operating
system not found, and does nothing.  I can reboot using a slink
rescue disk, and get into my system that way.  This isn't the most
happy thing in the world, though, and I'd really like the system to
work correctly.

I've tried reinstalling both LILO and the Debian MBR.  Neither
'install-mbr' nor rerunning 'liloconfig' seems to have had an effect.
Is there some important little piece of information in the boot sector 
that's gotten lost?  Are there any other hints for dealing with this
type of situation?  Should I just reinstall (not a major disaster, at
least if I wait until after my finals)?  TIA...
