Problem: DMA mode for IDE on ASUS CUSL2

[GeorgeD]

I've just upgraded to ASUS CUSL2 motherboard. Everything is working perfect, the only problem I have is this:

I cannot set the DMA mode for my IDE devices.

I have the Windows 95B (latest Win95).
When I installed the Intel latest i815E chipset drivers, the device manager found and installed the Intel ATA storage driver (which works OK) and the Primary and Secondary IDE (dual fifo), but these devices appear to be not working OK - there is an exclamation and the IDE devices are in the DOS mode.
I reinstalled the original Windows IDE Bus Master drivers and these are working OK (no exclamation, no DOS mode), but I cannot set my HD and DVD to operate in DMA mode (the checkbox is not present) and the transfer rates are horrible (half of the UDMA-33).
The original Intel ATA drivers are not for Win95.

Could anybody tell me what should I do, please? Thanks.
I don't want to install Windows 98.

ASUS CUSL2, Bios 1003 final
PIII - 667@667 (@800 rock stable, but I'm not an o'er)
