Hope the battery did not leak and damage the mother board.
If you do a search for this issue, a lot of data should come up as it is quite common. But there are also a number of variables.
Trident, is usually a video card.
The mass storage device may be a hard drive, f-disked to an unknown capacity, thus it is hard to tell you what to put in, but it will not be greater than 528MB. The Bios will not support anything bigger. It may also be a flash card, or a Disk on a module, etc.
Again, typically, boot the control, press CONTROL ALT and DELETE at the same time, this will reboot the control (you will need to attach a full size keyboard).
Press delete and it should go into your CMOS with standard settings highlighted. Press enter twice to get past a warning screen.
Set time, date, floppy type, hard drive parameters, and turn off the keyboard test.
There are too many variables to walk you through all the CMOS pages. Do you have a geek friend?
