Log in = ' logging out ' fix.

In case you get stuck with this problem:

Normally I boot to menu on IDE and default XP boot menu option is to boot
SATA1. A few months while testing some beta software, I had disconnected 2
SATA drives after doing a drive copy and had just the IDE hooked up.
Yesterday I turned the test box on again and reconnected those drives.
config = 1 IDE and 2 SATA's ( Seagate normally = SATA1 and Maxtor =SATA2)
Default boot to SATA and can't see SATA1. I checked and the power SATA1 had
not been reconnected so I did that. I then booted - menu defaults - starts
XP - get to logon screen and I login. However drive letter assignment is
bad. I realized that the first time I booted SATA since my 'normal drive'
wasn't hooked up, in the BIOS my first boot option for SATA drives is the
Maxtor. Restarted - checked - that WAS the problem. I changed the boot order
so SATA1 is primary boot again and restart. I can login but then get "
Logging Off" right after entering user pwd. .Removed SATA2
Disconnected all but SATA1 and works OK. Same with IDE. But with both
connected, IDE boots but SATA1 just gives " Logging Off" after entering user
pwd. .
..
Today I was going to repair XP ( recovery console). I need to check mail
first and rather than disconnecting the IDE cables, I just disabled in BIOS.
Booted SATA - it saw the IDE - correct drive letters - all better.

=======
if you have SATA and IDE bootable drives and IF you accidentally change boot
order and thereby reassign drive letters for a XP disk, DISABLE the IDE
drive in BIOS and boot SATA. once XP is working, it still sees the IDE
drive, reassigns the "correct drive letters" = fixed.
Made no sense to me - shouldn't DISABLED in BIOS mean 'the drive won't
work'? , but if I toggle enabled/disabled IDE the problem came and went.
With IDE drive disabled, I was able to boot SATA successfully AND IDE drive
was there - with proper drive letters.
I shutdown, rebooted, re-enabled IDE in BIOS and boots either fine now.

What problem? You haven't yet introduced or defined the problem.

Huh? The BIOS will boot using the bootstrap code (first 446 bytes of the
MBR) which is in the first sector in the first non-partitionable track on
the first hard disk that the BIOS finds dependent on the disk boot order
specified in the BIOS. So it sounds like your BIOS finds an IDE disk first
and gets the bootstrap code from that disk. That bootstrap code then reads
the partition table in that same MBR (master boot record) to find which one
is designated as the "active" tagged partition. It then loads the boot
sector from that active partition which then begins loading the OS. Only
then do you get Microsoft's "boot menu" to select which OS to load that is
listed in the boot.ini file (Vista+ changed this a bit but not regarding
what the BIOS and MBR bootstrap will do).

So my guess is that the first detected disk by the BIOS is an IDE device so
the MBR bootstrap from there gets used to load the boot sector for Windows
in the "active" partition on the IDE disk. The "Windows XP" selection in
the boot.ini file points to a partition on a SATA disk where is the rest of
Windows. Although the terminology sounds a bit backwards, you configured
Windows so its "system partition" (used to boot the loader for the OS) is in
a partition on an IDE disk and its "boot partition" is in a partition on a
SATA disk. While most users install Windows where its system and boot
partitions are the same, it is possible to install where they are different
and even on different disks.
A few months while testing some beta software, I had disconnected 2
SATA drives after doing a drive copy and had just the IDE hooked up.

Then were was the Windows that you loaded at that time? Previously you made
it look like the system partition for Windows was in a partition on an IDE
drive which loaded the rest of Windows from its boot partition that was on a
SATA drive. If you disconnected the SATA drive, just how would Windows get
loaded? If all you had left was the IDE disk then you must've changed your
Windows installation so the system and boot partitions were both on the IDE
disk (either as the same partition or as two partitions on the same disk).
Yesterday I turned the test box on again and reconnected those drives.
config = 1 IDE and 2 SATA's ( Seagate normally = SATA1 and Maxtor =SATA2)
Default boot to SATA and can't see SATA1.

Because when you only had the IDE disk you had changed your installation so
the boot partition was no longer specified as being on the SATA drive. For
you to boot Windows using the solitary IDE disk meant that *both* the system
and boot partitions for Windows had to be on just that IDE disk.

If you want to abandon the boot partition that you put on the IDE disk, you
will need to edit the boot.ini file so it points at the partition on the
SATA disk where you previously put the boot partition for Windows.

I checked and the power SATA1 had
