Может кто имеет опыт разборок с ISA картами в ноутах?

Звуковуха YMF715E-S (открывал ноут, смотрел на чип) на шине ISA

B BIOSe установлено так:
Base I/O:      220
WSS Codec I/O: 530
IRQ:           IRQ5
DMA:           DMA1/7

# modprobe sb io=0x220 irq=5 dma=1 dma16=7 (в dma16 неуверен)
# dmesg|tail

isapnp: Scanning for PnP cards...
isapnp: No Plug & Play device found
sb: No ISAPnP cards found, trying standard ones...
SB 3.01 detected OK (220)
sb: Interrupt test on IRQ5 failed - Probable IRQ conflict
SB DSP version is just 3.01 which means that your card is
several years old (8 bit only device) or alternatively the sound
driver is incorrectly configured.

$ play 8bit.wav
Звук есть (плохой) -- звуковуха рабочая.

Ничего не находит (может я им неправильно пользуюсь)
