Windows can't see extended partition logical drives

[Randy Wetzel]

I can't find any information in the archives of this group that helps
me with this problem.

I have 2 physical IDE drives in my system setup on a primary and
secondary IDE channel. I have Redhat 7.2 installed on the primary drive
with GRUB as the boot loader in the small /boot primary partition.
I have an extended partition with several logical partitions on this
drive for all the linux directories such as / and /home.
On the secondary drive, I have Windows 98 installed on the primary C
drive partition. I have an extended partition with drives D and E
as logical drives.

When I setup my BIOS to boot to D (2nd physical drive), Windows boots
perfectly and is able to see drives D and E with no issues.
When I setup my BIOS to boot to C (1st physical drive), GRUB works
great and boots linux perfectly. I can mount all the Windows partitions
with ease within linux.

However, when I ask GRUB to boot Windows, Windows boots but fails to 
see the logical drives D and E. Only C is seen by Windows.
Here is my GRUB config file:

default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz

title Red Hat Linux (2.4.7-10)
        root (hd0,0)
        kernel /vmlinuz-2.4.7-10 ro root=/dev/hda6
        initrd /initrd-2.4.7-10.img
title Windows98
        map (hd0) (hd1)
        map (hd1) (hd0)
        rootnoverify (hd1,0)
        chainloader +1
        makeactive

GRUB is so much better than LILO, I'd hate to have to go back to LILO.
I hope you can help me with this.

Regards,
Randy
