Tips for installing Windows 98 in QEMU/UTM

Windows 98 runs surprisingly well in QEMU via UTM SE, but it requires some care in setting it up. It’s a great way to run old 90s Windows and DOS software on your iPad (and Mac too, though you have other options available to you, or an iPhone if you don’t mind the HID difficulties). This post provides some suggestions and tips for installing Windows and selecting the best emulated devices. The guidance is intended for UTM users on Apple platforms, but should apply to anything QEMU based (or QEM

Booting 5000 Erlangs on Ampere One 192-core

Booting 5000 Erlangs on Ampere One 192-core Underjord is an artisanal consultancy doing consulting in Elixir, Nerves with an accidental speciality in marketing and outreach. If you like the writing you should really try the pro version. In the previous post on 500 virtual linux devices on ARM64 I hinted that I expected serious improvements if we got KVM working. Well. We’re there. Let’s see what we got going on. Disclosure: I am running a conference called Goatmire Elixir which Ampere is a sp

Hexagon fuzz: Full-system emulated fuzzing of Qualcomm basebands

Key takeaways 1. Due to Qualcomm’s proprietary architecture, a lack of security tooling exists around their baseband 2. Our tooling enables research on Hexagon baseband with significantly reduced engineering work 3. We release the first open-source toolchain for full-system emulated Hexagon firmware fuzzing at TROOPERS25 Overview Every phone has a cellular baseband processor to handle mobile communications (5G, 4G, GPS, and more). Qualcomm created a specific architecture for its baseband c

iPhone 11 emulation done in QEMU

QEMU README QEMU is a generic and open source machine & userspace emulator and virtualizer. QEMU is capable of emulating a complete machine in software without any need for hardware virtualization support. By using dynamic translation, it achieves very good performance. QEMU can also integrate with the Xen and KVM hypervisors to provide emulated hardware while allowing the hypervisor to manage the CPU. With hypervisor support, QEMU can achieve near native performance for CPUs. When QEMU emulat
