Use the following command to get some information on the original database:
load headeronly from (device)
This may give you some ideas on how the original was laid out. Also, pay attention to the details of the error you get back from the load database command. This is where it should tell you how big and how many devices there were on the original.
On 6.5 there is a procedure called sp_help_revedatabase. Unlike 2000, on SQL 6.5 you need to have an existing database, that has been built the same way as the original database. Run the procedure on the original server, and take its output, paste it in a query window to create the new database on the new server... After which, the restore should be a snap. This is off the top of my head, so you may want to look it up on BOL, or a search engine for the exact process.
This is assuming you have access to the original server that the database was dumped. If not, sorry.
