Model: CT4830 - SB Live
Operating System: Windows 95 (Note: might work with other versions of this os.)
Presario 5700T's have the Creative/Ensoniq "Sound Blaster AudioPCI 128" sound card using the Ensoniq 1371 & 1373 chipsets. Also known as CT-4830 Sound Blaster Live.
This is the driver uploaded straight from my restore disk and shows to be version 4.10.29, dated around March 5, 1999.
This driver set should be complete with midi files and mpu-401 support with the driver set.
File Size is approx 48.7 mb. total.
File Name: 151496.zip
Unzip to a temp folder and read the text or doc files. There are several setup.exe's so you may need to read the instructions to see what needed to be installed first, then 2nd, etc. I've never installed from this disk so I can't really say how to do it with accuracy.
Happy downloading...and I hope this gets your sound card running.
