Windows 98 - Qcow2

Nostalgic and surprisingly usable – but expect to tinker

Running Windows 98 in a modern virtual environment typically requires the emulator, which uses the QCOW2 (QEMU Copy-On-Write) disk format. This format is efficient because it only grows as data is added to the virtual disk . 1. Preparing the Virtual Hard Disk

qemu-system-i386 -accel kvm -cpu pentium3 -m 256 \ -drive file=win98.qcow2,format=qcow2 \ -nic user,model=ne2k_pci \ -vga cirrus

This command creates a 2 GB QCOW2 image named windows98.qcow2 . windows 98 qcow2

Modern virtualization solutions like VirtualBox or VMware often struggle to run operating systems as old as Windows 98 due to a lack of legacy driver support and compatibility issues. In this arena, shines, as it can emulate older hardware components that Windows 98 expects to see.

I rubbed my temples. Finding a replacement hard drive for a 25-year-old proprietary workstation was possible, but not in 24 hours. Installing Windows 98 on modern hardware was a nightmare of driver incompatibilities and BIOS settings.

Since I cannot browse the live web to retrieve a specific PDF file and send it to you directly, I have compiled a technical white paper below. This document details the process, challenges, and best practices for running Windows 98 inside a QCOW2 virtualization environment (typically QEMU/KVM).

While Win98 supports FAT32 [4], it is best to keep your virtual disk under 127GB to avoid legacy LBA issues. Step 1: Create the Virtual Disk

Once the installation is complete, you'll need to configure the virtual machine to use the QCOW2 image. You can do this by creating a new QEMU command:

* **Allocate sufficient RAM**: Windows 98 requires a minimum of 16 MB of RAM, but 256 MB or more is recommended for smooth performance. * **Use a compatible sound card**: Windows 98 may not support modern sound cards. You can try using the `sb16` or `es1370` sound card emulators. * **Configure networking**: You can configure networking in the virtual machine settings to access the internet or local network.

After installing Windows 98 and configuring the virtual machine, you can optimize the QCOW2 image by:
