weird boot problem

I replaced a ps/2 mouse with an usb mouse and then my system wouldn't boot.
I use lilo and it gave a '99' error over and over. Booted the gentoo install
CD, mounted my partitions and chrooted then rebuilt and reinstalled my
kernel. Reran 'dolilo'.

Still no joy. I had made sure I didn't have a camera card in my hp 8200
and that any other unusual usb devices were disconnected. Then I thought
about the mouse and removed it and reinstalled the old one. Then the
system was able to boot!

How the hell can a usb mouse prevent booting? Does it confuse usb-storage
and create a block device that slides in to replace /dev/sda? I was able to
boot the cdrom, but not the hard drive.

I don't know for sure what is going on, or why lilo fails, but I suspect
this is to do with a mouse related interupt being provided by the
computer for emulation purposes. I have seen an option on some computers
BIOS setting relating to the USB mouse. I think it is worded something
like "mouse available from boot" (on some systems it might be something
like "USB mouse provides legacy emulation")

If such an option exists on your system, disable it. You do not need the
mouse available at boot, unless you are using some sort of Apple
Macintosh emulation.

Yes, that is what it sounds like-- it was trying to boot from the usb
device. Why do you not disable usb booting in bios ( if possible) and see
if the same thing happens.

Does the BIOS allow you to choose the boot order at startup? It's often
done by pressing F12.

Or do you have a bootloader installed on your mouse? :-)

(Actually, you could boot from a USB mouse these days, some mice have
flash storage.)

no such luck. Hitting ESC, F10, F12 and others didn't bring up a boot menu

The boot page of the motherboard (an asus a8n-sli) had a priority selection with
stuff like "cdrom, hard drive" and then the ability to select what device(s)
constituted a cdrom or hard drive. The hard drive has top slot as the SATA,
with "plug in device" for #2 which should never be used.

This motherboard has had problems w/ usb. The power supply for the internal
usb was bad and I went with 2 4 port PCI cards to replace it. I had the mouse
going through a 4 port hub (I have a *lot* of usb on this system).

The mouse might also be defective, reporting a bogus ID and causing the system
to think it's a storage device. Maybe some new vista idiocy?

If the motherboard has a Phoenix BIOS, then whether you get a boot menu or
not depends on whether you leave the "devices index" expanded or not when
you save your BIOS CMOS settings.

By this I mean that several devices would be grouped in "indexes", e.g. an
"index" listing all the PATA hard disks in your system and simply labeled
"hard disk" or something like that. You expand/hide the list of devices in
that "index" by pressing the numeric plus/minus key. If you leave the list
expanded when you save the settings, you will get a boot menu on start up.

So far, I've only seen this on Phoenix BIOSes though.

I don't really think so, but on the other hand, there seems to be a tendency
now to develop the hardware in function of MS Glassware, rather than to
develop an OS in function of the hardware that it will be running on.

For instance, when AMD set out to develop the AMD64 architecture, Crimosoft
asked them to keep two particular segment registers - I have forgotten
which ones - in the AMD64 architecture - even though 64-bit long mode does
not allow for segmented memory addressing anymore - simply because
Glassware requires those two registers for something else.

It's an upside-down world, but then again maybe that's because Crimosoft
does not and never will understand how to design a real operating system.
They're so arrogant that they require the hardware vendors to tailor their
stuff to the crappy code, rather than to fix the code in the first place -
which would of course constitute developing a new OS from the ground up,
rather than "a new version of Windows".

Considering that Crimosoft have never developed anything of their own; all
they've ever released so far was bought/borrowed/stolen elsewhere and then
proprietarized - read: mutilated beyond functionality - so that it became
unique to Crimosoft. Basically, it's the same approach as what they've
always been doing to internationally agreed-upon standards, such as
W3C-compliant HTML, XML, Java, etc.

Embrace, extend, extinguish... Too bad the word "break" doesn't start with
an "e" or it could have been added to that list...
