I'm not familiar with Advent T9201.
Normally you would search manufacturer's website for users guide or recovery instructions for that model. It should tell you whether it comes with recovery partition on hard drive, recovery CDs, or both (and instructions on how to access). Look for a Downloads or Support link on the website.
A quick google came up with this. See if the Recovery Disc subsection of this link
Advent T9201 PC looks reasonable.
