VGA emulation doesn't support additional text modes including flashing
## Host environment - Operating system: Ubuntu in WSL2 with X-Forwarding - OS/kernel version: `22.04.1` - Architecture: `x86_64` - QEMU flavor: `qemu-system-i386` - QEMU version: `6.2.0` - QEMU command line: ``` qemu-system-i386 -cdrom os.iso ``` ## Emulated/Virtualized environment - Operating system: [TheDevMinerTV/os](https://github.com/TheDevMinerTV/os) - OS/kernel version: [git commit `919f8d46136138bf32e2131c17e9161158bbccb7`](https://github.com/TheDevMinerTV/os/tree/919f8d46136138bf32e2131c17e9161158bbccb7) - Architecture: `i386` - Download: https://github.com/TheDevMinerTV/os/actions/runs/4641628674 -> Artifacts -> ISO at the bottom ## Description of problem All of my physical machines use black as `DarkGray` and have the text starting from `White+DarkGray` blink (watch the video below). The ISO I'm using is a minimal kernel I've written to check VGA text mode (provided by the BIOS at `0xb8000` with a 80x25 resolution) handling on multiple emulators and machines. Changing the emulated CPU and display driver doesn't change this behaviour. Hyper-V: color test shows correct colors, all text starting from `White+DarkGray` is blinking ![Hyper-V](/uploads/0d6e9a2398d0f5aeca94e6fbbc31e055/image.png) AMD Athlon 64 X2 6000+ + NVIDIA Quadro 400 on actual hardware: same as Hyper-V I've tested this with multiple physical GPUs and they all have the same behaviour and color palette. ![AMD Athlon 64 X2 6000+ + NVIDIA Quadro 400](/uploads/883484cea78f8d598634ebab3645341c/image.png) QEMU: dark gray is the wrong color and the text doesn't blink Changing the emulated device doesn't change this behaviour. ![QEMU](/uploads/cf1e6a1e7e8bcfc48b60bd92d9024de5/image.png) I think QEMU should emulate the hardware as close as possible and therefore atleast have the blinking text. Consider this a low priority issue. ## Steps to reproduce 1. Download ISO from the link above 2. Run the QEMU command above 3. See the text not blink ## Additional information ![Demo of various machines](/uploads/9de70ecd2185bdb57b3ee324fe18dcd9/2023-04-08_04-56-05.mp4) <!-- The line below ensures that proper tags are added to the issue.
