I've just installed the ES1868F to my newbuild socket 7 system. It's a triangular shape.
The system is the following, Asus P5S-VM (flashed with custom bios of P5-99VM because it was HP branded), Pentium MMX 233 MHz, 32 MB SDRAM PC100, S3 Virge DX 4MB. I've also installed ES1370 but I'm not loading the driver, I didn't want to leave it to the 440Bx which Ι withdrawing.
I think it sounds better than the ES1370 PCI and I tested many games. Also I can hear CD sound without connecting the DVD-RW to the onboard controller of the sound card. Just entering setvol and incresed the cd volume, I have to do this all the time and not to modify the autoexec.bat. Also the card works with Windows 3.11 for Workgroups without issues. I'm using Dos 7.10.
Some games as FIFA recognized the card as SB 16.
Also not a single divide overflow that I was experiencing with the Celeron 400 and the 440Bx and of course I can make the MMx to run at 100 MHz. Also my K6-2 450 MHz can run at 100 MHz on this board.
Only issue that the SiS 530 is a little bit slower than the 440Bx on copying files. Also setting the Virq and the Ven_Dis to disable onboard vga is disabled and not shown and the Windows 95 device manager.
