They're normally splitting from some, but normally not all 9, of the same tapes as "classic", so you can take a look on the classic status-page

hihi, I just received a wu from september 2000. The tape must have been under a huuuge pile.

Maybe we crunch the same WU:
03.01.2005 14:10:57|SETI@home|Finished download of 16se00aa.8304.353.173580.23
[EDIT] UTC+1

No probs with those old WU's;-))

Keep on crunching

> 64 meg of ram IS the minimum required to run the program now.

I have a very hard time believing that it needs exactly 64 MB as a bare minimum. I understand that the older WUs specify that they need 32 MB, but I have seen for myself that, when processing them, the program actually uses just under 16 MB. If the machine actually had only 31 MB available to Windows, it wouldn't notice the difference, but BOINC would refuse to download the WUs.

I have to assume that, when processing one of the newer WUs with the 64 MB minimum RAM spec, SETI may actually be using 30 to 32 MB, in which case my 63.2 MB of available RAM would work fine. By specifying a minimum RAM size equal to approximately twice what SETI actually needs, they provide a comfortable margin for system overhead. All I'm asking is that the margin be trimmed a wee bit so that BIOS shadowing won't eliminate an otherwise suitable crunching box.

That would be easy enough to do if the box were in my home, but it belongs to my employer. The only reason we keep it around is because it's the only box we still have that supports dual floppy drives. We use it when people suddenly discover that they need some old project data that was squirrelled away years ago on a 5.25" floppy. There's no way they'll buy additional RAM for it just to let it run SETI/BOINC.

-------- please excuse me I am sorry to be off the topic ---------

Hi Clay ,

from byron


but I just wanted to say thank you to Clay Ruth as founder of:

the <B> SETI@home Planetary Society team.</B>

Because:

I think it was in 1997 or 1998 that Dr. David Anderson and Dr. Dan Werthiner went to the Planetary Society , with this idea of giving sofeware away for free and then asking people to install it on their computers to look for ET ----- to ask for the funding to start SETI@home. the Planetary Society were the first people to put up the first money , I think it was $ 50,000 to start. so if it were not for The Planetary Society we probably , would not have SETI@home

so , if you are looking for a team to join , I encourage you to join the <B> SETI@home Planetary Society team.</B>

if I Made any mistakes about the history of SETI@home , I am sorry, and someone please correct me

Regards and Best Wishes to Clay Ruth

friendly and respectful

Thank you, Byron.

I don't know the exact numbers involved, but the concept is correct: Without the support of TPS, there would be no SETI@home. TPS provided the initial funding that got SETI off the ground, and it continues to be a significant source of the funding that keeps SETI going -- not only SETI@home but other aspects of SETI as well. Joining TPS is exactly what Dr. Carl Sagan would want people to do -- after all, he was its co-founder.

@Clay

Hints :
- Turn off BIOS Shadowing, has no performance effect nowadays anymore
- if still running Win9x, you can free some RAM by the following Tweaks :

CONFIG.SYS
----------
DEVICE=C:WINDOWSHIMEM.SYS
DOS=HIGH,UMB
DEVICE=C:WINDOWSEMM386.EXE NOEMS I=B000-B7FF HIGHSCAN

(the I=B000-B7FF will use RAM formerly reserved for Mapped Hercules Graphic Modes which noone uses since 15 years now; HIGHSCAN will use a more aggressive way of using upper RAM below 1MB - if problems arise, remove the HIGHSCAN Option)

MSDOS.SYS
(hidden, write protected System file)

Modify existing or create new entries :
---------
DrvSpace=0
DblSpace=0
Loadtop=1

(will not load DriveSpace Driver, will not load DoubleSpace Driver -obviously don't use this if you've enabled DoubleSpace on the HardDrive- , and loads Command.com into upper part of 640k Area)

These Tweaks will free up as much RAM as possible under MS-DOS and Win95/98/98SE and WinME.
Windows and BOINC should see your System as equipped with a full 64MB afterwards.

If nothing else works, old Software like RAM-Booster "can" help to gain a bit more RAM (the biggest effect is that more free RAM is reported to Windows and its Applications); dirty trick but should get BOINC working just fine as well ;)

I wish I could! The BIOS setup offers no such option. It's an Intel AL440LX motherboard. It had BIOS rev P09, which during boot-up reported that it was shadowing the BIOS and video ROMs. I went to Intel's site and downloaded the last BIOS offered for that board, rev P14. It updated successfully; I applied system defaults and then reinstated my custom settings, but still there is no option to disable shadowing. During boot-up it no longer reports that it is shadowing, but indeed it is, as Windows reports 64,940 KB RAM, which translates to 63.4 MB, not 64 MB.

No; this box has NT4.

Now that sounds like a good possibility, if it will work on NT4. I'll check it out. Thanks!
