If it is really a LTR-52246S, then it is a LiteOn. And you shouldn't have any trouble installing it on Windows 98. Memorex, who sells the same drive under their own name, lists requirements as Windows 95/98/2000/NT 4.0/ME/XP, Pentium 166 or higher.
There shouldn't be any need to install ASPI. Just physically install the drive and the included burning software.
