Coming at your question from the other angle, there is a Filipino bicycle manufacturer called MOB for "Men on Bikes." They claim to have been selling since 1998, so there's some overlap with the Schumacher stint at Ferrari. I tried the Wayback Machine on their website to see if I could look at old models, but either there weren't snapshots of the site that long ago or they used to have a different website address.
You could visit theirMOB's contact form with a link to your question and/or your serial number.
I found some pictures of old MOBs on Facebook. They can't be your bike because they don't have the extended top tube where "MOB" is stamped into the butt of yours.
I'm curious about the down tube, though. Yours looks like it has a continuous cross section of a rounded triangle. It's hard to tell in the photos below, but the bright yellow 2001 mountain bike might have the same tube shape, even though its top tube is clearly a different angle than yours. It would make more sense to have the top tube extension when it's more horizontal, so the fun stamped butt might not have survived an industry-wide change in geometry.
Your frame has also cable stops in a different place and no mount for rear disc calipers, but your bikeit could be an early or rare model.
