Audio issues and USB missing in Basic Linux (slackware 4)

Hey everyone,

I have an old laptop (pentium 1, 64mbs of ram) that I have installed FreeDOS on. Lately I have been playing around with Basic Linux which is a kind of Slackware 4.0 minimal boot floppy from the late 90s.
Everything is being great, I actually got to learn a few things about GNU/Linux and terminal usage and all... BUT I can't get the sound to work properly. It sounds as if it was played in slow speed and the voices are all wrong.

My laptop has a Yamaha OPL3, which in DOS works perfect as a SoundBlaster compatible.
I tried setting the soundcore, sound, uart401 and sb modules, all worked, and tried usin the standard line for sb io=0x220 irq=5 dma=1 dma16=0 mpu_io=0x330. The sound started working but it sounds really bad.

A second problem is I can't get linux to see/mount my usb drive which is a pain (I have been using DOS to copy files over to the laptop before botting Linux).

Anyone has experience with old Slackware and can give a hand?
THANKS
