I have an athlon 850 tbird with an old 2 GB HD and old toshiba CDROM. When I install Win98 se, everything goes ok until the end where the CDROM drive disappears and I can no longer finish installing the last files (since it can no longer read the win 98 disk). Even with this, the OS seems to work. I just can't get a CDROM drive. I think this happened to me before with an older computer. But the CPU and mobo are new. Just the HD and CDROM are from old systems. Anyone have a similar problem?
