This board (Zida Tomato Board PG133)will come up with a invalid system disk when there is no disk in A:\. In BIOS everything looks OK, hard drive and CDrom are there everything looks in order. Sometimes when you restart it hangs, now it is stopping on the invalid disk. Boot to floppy and check drive C:\ and it tells you that there is only one file there when in fact it has WIN98 ON IT. I have run microscope9 and the hard drive and board is fine. Spinrite5 has checked the drive with no problems.What do you think?
