Trying to boot via grub4dos without cd

[elliot s]

I once again tried to install ReactOS via grub4dos starting from a win98 setup.
grub4dos successfully runs Puppy Linux.frugal install.
Previously, i was on a scsi system. This time it's all ide.
Install hangs after ndis.sys line. I tried the atapi.sys -> uniata.sys patch.
No difference.
I'm using grub4dos version 0.4.4
Is the win98 mbr going thru io.sys the problem?
How does anyone else do a cdless install that includes windows?

map.lst entry:

map  --mem  (hd0,0)/ReactOS-LiveCD.iso  (hd32)
map  --hook
chainloader  (hd32)
boot
