I have an old NEC computer, specs are PI - 75MHz, 64MB RAM, 1.2 GB HDD, 
(2) Linksys 100TX NIC cards.

The system doesn't support CD-ROM boot, so I took out the hard drive and 
used the physdiskwrite.exe program  on another computer to write the 
image to the drive.  Everything writes fine, I can even examine the disk 
afterwards and see that it has created the partition properly.  When I 
take the drive and install it back in the machine, the system gets a 
"read error" while trying to boot the drive.  I took a look at the drive 
in a raw mode and noticed nothing in place to bootstrap the OS?  Is the 
generic-pc-1.21 image missing all the bootstrap information?  I know the 
drive is good, I can install Windows 98, Windows NT, even FreeBSD 4.11 
and they all work fine.  What am I missing? Is there something more that 
needs to be done after you load the image to make the hard drive 
bootable on the PC?

Any help would be greatly appreciated.

Thanks,
Michael
