先别更新区块链下载。用别人的区块链下载时，不要拿最新到头的。稍微旧一点的更好，这样它才能下载并校验最近的区块。
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 的 4 路 SSE2 SHA-256 在 sha256.cpp 里，几个修订之前就上传了。
tcatm's 4-way SSE2 SHA-256 is in the file sha256.cpp and already uploaded a few revs ago.
我刚刚上传了 rev 134，是 makefile.unix，让 Linux 上可以用它构建。现在在 Linux 上构建 rev 134 就会得到 -4way 开关。
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.
如果你因此构建出问题，就编辑 makefile.unix 然后：
bitcoin: $(OBJS) obj/ui.o obj/uibase.o obj/sha256.o
bitcoind: $(OBJS:obj/%=obj/nogui/%) obj/sha256.o
If you have problems building because of it, then edit makefile.unix and:
bitcoin: $(OBJS) obj/ui.o obj/uibase.o obj/sha256.o
bitcoind: $(OBJS:obj/%=obj/nogui/%) obj/sha256.o
我构建的 0.3.10 Linux 版会带 -4way 选项。
The 0.3.10 linux build will have the -4way option when I build it.

步骤：
Steps:
1) 关闭客户端。
1) Shut down.
2) 下载 knightmb 的 blk 文件，替换你的 blk0001.dat 和 blkindex.dat 文件。
2) Download knightmb's blk files and replace your blk0001.dat and blkindex.dat files.
3) 升级到 0.3.10。
3) Upgrade to 0.3.10.
4) 启动时应该少于 74000 个区块，让它重新下载剩下的。
4) It should start out with less than 74000 blocks and redownload the rest.
或者，如果你不想折腾下载 blk 文件，直接这样做：
Or if you don't want to mess with downloading blk files, you can just do this:
1) 关闭客户端。
1) Shut down.
2) 删除（或移走）blk*.dat
2) Delete (or move) blk*.dat
3) 升级到 0.3.10。
3) Upgrade to 0.3.10.
4) 它会重新下载全部区块，大概要一个小时。
4) It redownloads all blocks, probably take about an hour.
