Fortunately, I saw someone at driverguide.com uploaded the driver for the built in vga. There's also available sound and modem driver. But the problem is, after downloading, the modem is still looking for the driver. Also, the first vga driver that i downloaded was only meant for Windows XP. So i download another one, and it works. After a little research I found the correct driver for the modem and soundcard at the ESS website. I notice that the file that was uploaded in driverguide is for Win95 and Win98 first edition, so that is the reason why it didn't work.
Here's the download links for those of you who also need it:
