P4C800-E - Cannot load CDROM driver in DOS utility floppy

I use bootable DOS FDs and CDROMs for various system utilities (Drive
Image, Partition Magic, etc). With previous motherboards, I could put
a line like "device=oakcdrom.sys /D:mscd001" into the CONFIG.SYS file
and the MSCDEX line in the AUTOEXEC.BAT, and the CDROM would work.

With the P4C800-E, the CDROM is not found when OAKCDROM tries to load.
Device manager tells me the Intel 82801EB Ultra ATA Storage controller
is at IO EFxx, Memory FFEFFCxx, and IRQ 18. The CDROM works fine in
Windows XP.

Are there command line switches for OAKCDROM.SYS to set these
parameters?

Is there another driver that can support a DOS CDROM on the P4C800-E?

Is there a way to set the BIOS to make the ATA controllers settings
compatible with OAKCDROM.SYS (or any other available ATAPI DOS
driver)?

 

hmm, is your cdrom attached to the promise controller?
cheers

 

The CDROM is attached to the Intel ICH5 (82801EB) ATA controller. This
has two SATA ports and two PATA ports. The SATA ports (IDE1 and IDE2)
are unused. A hard drive is attached as master to IDE3. There are two
CDROMs as master and slave on IDE4.

A different PATA hard disk is attached to the promise controller,
which is operating in ATA mode (not RAID).

 

My old standard Windows 98SE boot disk with CD ROM support worked fine
on mine. The CD ROM is on the secondary IDE channel.

Why don't you start with something like this and work backwards?
