关于6.3下面AC97驱动问题

各位高手:
本人在使用AMD LX800一个PC104的板卡,操作系统是6.3.2的。板卡自带AC97芯片。音频信息如下:
Class = Multimedia (Audio)
Vendor ID = 1022h, Advanced Micro Devices [AMD]
Device ID = 2093h, CS5536 [Geode companion] Audio
PCI index = 0h
Class Codes = 040100h
Revision ID = 1h
Bus number = 0
Device number = 15
Function num = 3
Status Reg = 2a0h
Command Reg = 5h
Header type = 0h Single-function
BIST = 0h Build-in-self-test not supported
Latency Timer = 0h
Cache Line Size= 8h un-cacheable
PCI IO Address = d800h length 128 enabled
Subsystem Vendor ID = 1022h
Subsystem ID = 2093h
Max Lat = 0ns
Min Gnt = 0ns
PCI Int Pin = INT B
Interrupt line = 11
CPU Interrupt = bh

我通过io-audio -dgeode或者io-audio -dac97加载的sloginfo信息如下

Jun 08 02:15:23 1 7 0 mount_card(): failed to initialize card geode

可以肯定是相关的库文件我都放到了dll目录下,但是不知道为什么提示库初始化失败。不知道高手有没有碰到过类似情况。
