Dead Host Question

(moderation:
My old 500GHz Gateway fell victim to the storms/power interruptions that hit our are last weekend (Marietta, GA). The Gateway is beyond reviving (and I am in the process of procuring a replacement) but I do hope to salvage the data from its HD (including the BOINC folder).
My question is: Since the old host has a few unfinished WU's assigned to it, is there any way of transferring them to the new computer? Alternatively, is there any way of aborting these WU's so they can be reassigned? Or, is the "deadline" the only answer?

Iff the "old" and "new" hosts are *mergeable*, meaning same hardware and OS.
Then after attaching the new host goto "Your Account" and merge both host.
All WUs from the old host are now assigned to the new host (after the next
scheduler request).

Michael,
I should have specified that the new host will be a P4 and 2.4 GHz (whereas the old one was a P3). However, the OS will be the same (XP Pro).

They can't be merged. So the WUs will time out eventually.
So let's hope you can salvage the BOINC folder...

Stick,
That's some bit of sucky luck, amigo. I guess we can be grateful it wasn't the laptop, huh?
Let me know if you need any help assembling the replacement, or are you going to go the store-bought route?
In both good times and bad, friends rule!

If you are still using the same motherboard (faint hope as a P4 won't fit on a P3 mobo ;)), changing CPU and RAM won't make a new hostID. I know, I've done it. Changing only the P4 Celeron 2.3GHz and 512MB of PC-133 RAM to a P4 2.8GHz with 1GB of DDR333... all over the place my hostID stayed the same, while it just updated the CPU/RAM change.
Now, what you can try is to move the harddrive with BOINC on it to the "new" computer. Reinstall BOINC and maybe that it will continue with the work it still had.

Jord,
Thank you! It worked. All I did was drag my BOINC folder to the Program Files folder on the C drive of my new computer and then reinstall BOINC. The new computer picked right up where the old one left off. It is using the same old Host ID, but my account data on the server has been updated to reflect the new computer info. For the record, the only constant was the OS (XP Pro). The motherboard and processor are completely different.

EDIT: Also for the record, I used the BOINC "Single User" installation option on both the old and new computers.

Great. :-)
I'll have someone add that to the Wiki.
One thing I forgot though: Always do a new benchmark when you change CPU. Just in case BOINC itself doesn't do it, else you'll be crunching with the old benchmarks for up to 5 days, when BOINC does the auto-benchmarking.
RE: Great. :-) I'll have

BOINC (v5.2.13) did the benchmarking immediately (by itself). I know this because, for a short time, I thought what I did what not going to work (i.e. all my work was showing up as suspended/preempted). Then, when I looked under my "Messages" tab, I saw that it was just because BOINC was already running benchmarks.
While we are on the subject, I just remembered something else a little strange. The BOINC folder (that I dragged and dropped into my new Program Files folder) had the Trux BOINC Client in it. When I "reinstalled" BOINC (after the drag and drop), I expected the standard BOINC Client to be "back in place". Not so. The Trux Client was still there. (i.e. I guess the "reinstall" only updated BOINC Manager.)
As far as I know, a reinstall
)
As far as I know, a reinstall as well as a repair, will only fix the entries in the registry. That with the old client, at least.
BOINC 5.3.x and 5.4.x that we're testing deletes all the old files and puts in the new ones. Then again 5.4.1 this afternoon wanted me to close my browser (Mozilla Seamonkey), Trillian (the chat client) and Solitaire (!!! of all things), before it would allow the installer to continue. ;-)

I have not had any of these problems with the latest versions. I have one host that wants internet explorer closed but the others let me leave it open. That host quit asking for IE to be closed for one or two versions after I did a clean install on it but has started again.
