Don’t update the block chain download. When you take someone’s block chain download, you don’t want it right up to the end. A somewhat old one is better so it can download and verify the most recent blocks.
tcatm’s 4-way SSE2 SHA-256 is in the file sha256.cpp and already uploaded a few revs ago.
I just now uploaded rev 134 which is the makefile.unix that enables building with it on Linux. If you build rev 134 on Linux now you’ll get the -4way switch.
If you have problems building because of it, then edit makefile.unix and:
- remove -DFOURWAYSSE2
- remove obj/sha256.o from the end of these lines: bitcoin: $(OBJS) obj/ui.o obj/uibase.o obj/sha256.o bitcoind: $(OBJS:obj/%=obj/nogui/%) obj/sha256.o
The 0.3.10 linux build will have the -4way option when I build it.
Here are the patch downloads for Windows:

Steps:
- Shut down.
- Download knightmb’s blk files and replace your blk0001.dat and blkindex.dat files. http://knightmb.dyndns.org/files/bitcoin/blocks/ http://rapidshare.com/files/413168038/BitcoinBlocks.torrent
- Upgrade to 0.3.10.
- It should start out with less than 74000 blocks and redownload the rest.
Or if you don’t want to mess with downloading blk files, you can just do this:
- Shut down.
- Delete (or move) blk*.dat
- Upgrade to 0.3.10.
- It redownloads all blocks, probably take about an hour.
