I dont think there is a direct path open any more.
DOS is not recognised by XP in any version.
Which way have you gone -
Installed XP on an oldish computer,
Re-used an old sound card in a new computer?
XP ought to be quite clever in finding suitable drivers, though if integrated, the motherboard's own drivers ought to be installed.
It may be loss of old faithful twiddles you miss, but if you explore to see what is already there you may be able to find free downloads that substitute quite well in the missing areas.
