lost Dos partition-dos seen from linux

[Harry Park <hpark01 sprynet com>]

I have 2 disks. c:is dos
d: is partitioned 880 megs dos 3.2gigs linux
I upgraded to rh7 this weekend. when the system boots the only drive I
have is c although bios sees the other drive. I did partition magic the
large drive down to 800 gigs from 2 gigs. and I did not test to see if
the 2nd drive was available after doing so. I just went ahead and
upgraded to rh7. I notice there is a partition type in fdisk listed as
partition magic. Could changing to this type of partition solve the
problem? currently the partition table looks like

Name Flags Part Typ FS Typ [Label] Size (MB)
hdb1        Primary FAT16   quantum  888.34

the rest are ext2

I can see the dos data on the second drive under linux, I just can't see
it from Windows. I also may have screwed up in the upgrade by pointing
to the second drive hdb in the lilo configuration. I now have to boot
from floppy to get to linux since my old method (loadlin) no longer
works. 

Help.....
