Can you type anything and show up on the screen ?
Because it's looking for the date and time I am thinking the cmos battery may be low or bad
It can also explain the second error since it cannot hold the settings
What happens when you press f2?
Can you set the date and time ?
If you can try to reboot (without turning the computer off) to see if it holds the time
If you have the same error you may need to replace the cmos battery
If it was just the date I think it's just a Dos thing
You can try to do this and see what happens
1. Type: date and press return.
2. If the correct date is displayed, simply press return. If the date is incorrect, type the correct date and press return.
3. Type: time and press return.
4. If the correct time is displayed, simply press return. If the time is incorrect, type the correct time and press return.
