As its name says, OldBiomes aims to the servers that were already existing prior the beta 1.8 version. When the beta 1.8 version came, the biome system was rewriten, using fractal instead of temperature and humidity like it did before. The server then had two choices: - To create a new map - To have incoherences in the map, like a desert... under some snow, a tundra considered as a desert or some boats the server users created blocked by ice.
The 1.2 introduced a really awaited feature with the Anvil format: The biomes are now stored in the map files, and not generated dinamically with the seed. It's here that OldBiomes takes it function: It use the legit beta 1.7.3 biome generation code for each block collumn in the selected radius and for each, save the correct biome.
Please verify your worldseed is correct in your level.dat! If the worldseed isn't the one the world generated with, incorrect biomes will spawn according to your seed!

And, about the precision of the biome algorithm: Before the use of OldBiomes:
After the use of OldBiomes:
/OldBiomes <length> (alias: /ob) : Use OldBiomes in a square, with the player in the center and the length parameter the length of the square. You need to disconnect then reconnect to see the changes.
/Unfreeze <length> Unfreeze the Y-top block for each collumn in the selected radius. If length is more than 2000, may be very RAM-consuming and may take some time.
1.0: Added unfreeze command.
