Another OEM system, but this seems to be a motherboard that was used in multiple Gateway systems from around 1997.
Motherboard appears to be based on an Intel design, might be a clone of an Intel board but with a Gateway customized BIOS. This was possibly used in various different models used throughout the late Pentium era. I actually had a Gateway system that was in a similar time frame, but we had it second hand and the original owner had wiped it in favor of a fresh Windows 98 install.
Supports up to 128MB RAM
Supports CD-ROM booting
No sign of USB, 86Box cannot interface with USB currently
Install/Recovery CD
You will get the option to format as FAT32 or FAt16, whichever one you choose will depend on what build of Windows 95 you have, this restore Cd does not feature a Windows 95 install, instead it contains a set of drivers and utilities that are installed in conjunction to Windows 95, but you must use your own Windows install disk instead.
FAT32 is supported on OSR2.1 onwards, whilst earlier builds use FAt16, if in doubt choose FAT16. I believe you can ‘Upgrade’ to FAT32 once you update the OS.
One potential issue here was the IDE CD-ROM driver, the restore CD gives you the option to choose, possibly because some systems might have used a propriety CD-ROM interface, or might be using the IDE interface on the soundcard instead. This could potentially cause issues if you choose the wrong option. For this I chose the Generic IDE-ROM driver, which can be found all the way at the bottom.
Once you begin the restore process you are requested to insert the Windows 95 install Cd and reboot, of which the system will begin to copy the Windows 95 files.
From here setup runs like a typical Windows 95 retail install, however on mine I encountered an error with the OEM serial number, and had to manually enter another one. I’m not sure of eyes are specific to the OEM version they were bundled with, or if each manufacture uses a slightly different algorithm, or maybe something failed to validate in the background.

Reboot, then Gateway software proceeds to install


Installs keyboard multimedia utility, then install utility freezes. I had to force a reboot at this point


A quick reboot and it then installs McAfee Anti-Virus

Installs DirectX 5, reboots again. Kind of redundant since OSR2 already included DirectX 5

Installs Microsoft Intellipoint, Gateway possibly bundled the Microsoft mouse with their systems


Lastly the sound card software install, Windows had already detected the SoundBlaster on install, but here it inclused the Creative sound software.
Post Install
Megaphone

Appears to be a modem and address book software to manage internet connections and user contact information.
AudioStation2

A MIDI and CD player with a Hi-Fi like interface, something similar was also installed on the Sony VAIO PCV-90
Adding a second drive
The motherboard has two IDE channels for a total of four IDE drive, with the SoundBlaster 16 PnP card we can also add an extra two for a total of six IDE devices.
Adding the second IDE drive, I encountered a problem since after adding it as IDE slave (0:1), Windows 95 would freeze upon bootup. The way to fix it was to use the Windows 95 bootdisk, use the FDISK /FPRMT command to initialize the salve drive, format as FAT32 (Or FAT16 if you are using an earlier version of Windows 95), then reboot and format within the boot disk.
After then would Windows 95 boot up and mount the drive.
Preinstalled Software
This was a bit dry, I presume Gateway didn’t bundle much with their systems or this is typically stored on another disk. From browsing the CD-ROM it’s a generic recovery disk with a range of drivers that covered the hardware that gateway would have shipped in their desktops. Any additional bundled software would have been shipped on a separate disk.
Even the OEM branding was scarce, I expected there to be a cow-skin themed wallpaper like the cardboard boxes used
Adding additional devices
PCI: Video Card (S3 Trio64)
PCI: 3D Accelerator (3DFX Voodoo)
PCI: For future use
PCI: For future use
ISA: Ethernet (AMD PCnet-ISA)
ISA: For future use
ISA: Soundcard (SoundBlaster 16 PnP)
PCI slots are based on the amount found on the Vogons wiki, there are four PCI slots in total but there may be many more as this board could optionally come with onboard video (This could be AGP?) Or sound.
Some versions of the board came with an onboard S3 Trio64, the Phoenix in 86box was the closest match and as a bonus was automatically detected and installed during instillation.
