forcing win 98 driver to load instead of FIC

I've got an old PA2013 motherboard which I've had to reinstall win 98 on
because of a virus. However, I loaded the FIC drivers that came on the
CD-ROM and realize that I should have used the win98 drivers instead as
recommended by FIC. For a start, I can no longer see the DMA check bos under
devices for the CD-ROM and hard drives. If I delete the Hard drive
controller driver, then windows will reload the FIC driver. How can I get it
to load instead the win98 driver?
Thanks.

It's OK, an uninstall is available on the CD itself. I have found that the
win 98 drivers are much faster, but when I check the DMA for the CD-ROMs and
use them, win falls over. Sadly it looks as if I can't use DMA. Seems
astounding that VIA recommend using the win98 drivers when there is
obviously a problem. The VIA drivers, although slower, seem to work with the
CD-ROMs.

what brand CD ROM ? not all CD ROM can use DMA, and you have to use at
least 64 MB ram to use DMA

64meg of dram is NOT required to use DMA mode, as I had DMA mode
working for a long time with 32M and then 48M of memory on an Intel
chipset based mobo. VIA noted in some of it's release note files that
it's busmaster driver is needed to correct access problems with some
cdrom and dvd drives (as I vaguely recall).

I was under the impression that one must have 64 MB to use DMA
effectively with 98, I mean there has to be a limit ! like what would you
say the low end of ram would be to use DMA ? 8 MB ? just because the box is
enabled doesn't mean it's working ~

DMA buffers are not necessarily that large, if you peruse the System
devices in Device Manager in win98, you can find a setting for the
Direct Memory Access controller where you can reserve up to 64Kbytes
for DMA buffers. How the protected mode drivers make use of DMA mode
in hard disk interfaces is beyond my understanding of the file system
drivers and controller chips. It is quite possible that a large data
buffer is not required, and that the HD controller chip performs
transfers from the HD to system memory in fairly small chunks
(remember the ATA HD data interface is only 16 bits wide) though those
chunks may be arriving at a high rate of speed.
