Introduction
I am testing an MSI MS5158 socket 7 motherboard, PCB version 1. Currently, it's got a Pentium MMX 233 in it (running at 200 MHz at the moment), and a couple of sticks of 60ns FPM. I managed to get a large socket A/462 cooler attached to the CPU socket. There's no need for this, but it looks good.

The mobo

1) Link to the mobo's BIOS file version 1.4. Filename is w5158v14.exe.
2) Link to the original BIOS file version 1.0, saved using Award Flash version 5.35A. Filename is awdbak.bin
3) Link to the original BIOS file version 1.0, saved using UniFlash 1.40. Filename is backup.bin
4) Link to the Stason webpage diagram for this mobo.
5) Link to the Intel chipset driver. Filename is infinst_enu.exe

Notes
1) I don't know if this is the latest version for this mobo. I discovered another version (2.1), but the release notes said that it worked for PCB version 1.1. My board is version 1, so I did not use this version. There is also another version available (2.0), but I guessed that was for the PCB revision 1.1 as well. The latest 1.x BIOS version I could find was 1.4, but I only briefly looked on DriverGuide. MSI had nothing, inside their poor legacy archive section.

2) This exe package includes an AwdFlash utility, appropriate to the era of this version 1.4 BIOS file, circa 1998. It is version 5.35A. It worked OK. It saved a back up BIOS file, and also flashed the board OK.

3) I ran UniFlash, and I was going to use it to flash the board, but I decided at the last minute to "risk" using the AwdFlash utility. Luckily it worked without any problems.

4) Jumper JP2 needs to be in the "enabled" position for BIOS flashing to be allowed.

5) This seems to be the same chipset driver package I use for my i440BX slot 1 motherboard, when I am using Windows 95. I am surprised by this.

The BIOS - initial version 1.0

UniFlash version 1.4

Award Flash utility, version 5.35A

Updated BIOS - I used Award flash 5.35A

After chipset installation
The "? PCI Bridge" device has disappeared which is good, and extra resources have now appeared in the System area. The chipset driver I used is in link 5 above.

if you have any i430 series boards, I have the latest triones drivers.... they are newer than anything you'll find out there... that's because my copy is legit! 😁 They work fine even in virtualized DOS systems, but some stuff may interfere with it and causes lockups on boot

Please can you explain a bit about these Triones drivers? Do they replace the Intel chipset driver (link 5 above) that I am using? Or are they for Windows 3.x? Thanks a lot.
