Dave: I hope you're following this thread still, because I have a solution for
you ...
On my ABIT board, I ran into this very issue with XP and XP 64bit. XP32 is on
my SATA RAID, and XP64 is on the IDE drive. And I noted the near identical boot.ini's
on either drive, and with my XP64 CD in the drive, XP64 on the IDE drive eventually
boots ...
Here's the trick: digging around with XP32 booted, I noted that somewhere in the
properties, the SATA RAID actually shows up as "drive 1", and the IDE drive shows
up as "drive 0". So as much as you might not want to hear this:
Set your BIOS to boot to your IDE drive first. Add the info for your SATA OS (since
I have XP64 seeing the RAID, I could copy the line from the SATA's boot.ini and put
it in the IDE's boot.ini), but change the "rdisk" value to 1 for the SATA based OS.
Note that I'm about 99% certain that if you used this boot.ini with the BIOS set
for the SATA RAID to boot, it won't work! Somewhere along the line there's some
translating and switching going on; I'm guessing that, with the SATA RAID set to
boot, during most of the boot up (I'm guessing) the SATA RAID is thought to be rdisk
0. But once it's booted, it probably becomes rdisk 1. (However, I'd be curious
to see if anyone has had a SATA RAID and an IDE drive both in the machine during
the install of an OS to the SATA RAID - I think in both my case and Dave's case,
we added the IDE drive later - I'd do it if it weren't for the fact that both my
OS's are currently running and I don't want to muck with them).
I went one step further and changed the default to boot to XP32 (off of the SATA
RAID). So if I power on the machine and wander off, even though the XP64 drive
is doing the boot loading, XP32 will boot.
One final note: on my XP32 OS, I tend to hibernate it at the end of the day. Note
that when I do this, I don't get a boot menu when I power on the machine - the XP32
OS resumes. While this may not make 100% sense, I actually prefer this behavior.
And, just in case anyone who reads this is curious: I haven't gotten too far in XP64;
I do note some key missing drivers:
- The USB - Serial port I have for my dive computer
- The USB drivers for my Sony camera
- And I have an old USB web cam that I doubt has drivers
Someday, should Sony update the drivers for my camera, I might reverse (oy, would
that be a PITA though) the setup and have XP64 on the SATA RAID.
