And the (SeaBIOS) winner is... 4a6dbcea3e412fe12effa2f812f50dd7eae90955 is the first bad commit commit 4a6dbcea3e412fe12effa2f812f50dd7eae90955 Author: Nikolay Nikolov Date: Sun Feb 4 17:27:01 2018 +0200 floppy: Use timer_check() in floppy_wait_irq() Use timer_check() instead of using floppy_motor_counter in BDA for the timeout check in floppy_wait_irq(). The problem with using floppy_motor_counter was that, after it reaches 0, it immediately stops the floppy motors, which is not what is supposed to happen on real hardware. Instead, after a timeout (like in the end of every floppy operation, regardless of the result - success, timeout or error), the floppy motors must be kept spinning for additional 2 seconds (the FLOPPY_MOTOR_TICKS). So, now the floppy_motor_counter is initialized to 255 (the max value) in the beginning of the floppy operation. For IRQ timeouts, a different timeout is used, specified by the new FLOPPY_IRQ_TIMEOUT constant (currently set to 5 seconds - a fairly conservative value, but should work reliably on most floppies). After the floppy operation, floppy_drive_pio() resets the floppy_motor_counter to 2 seconds (FLOPPY_MOTOR_TICKS). This is also consistent with what other PC BIOSes do. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1840719 Title: win98se floppy fails to boot with isapc machine Status in QEMU: New Bug description: QEMU emulator version 4.1.50 (commit 50d69ee0d) floppy image from: https://winworldpc.com/download/417d71c2-ae18-c39a-11c3-a4e284a2c3a5 $ qemu-system-i386 -M isapc -fda Windows\ 98\ Second\ Edition\ Boot.img SeaBIOS (version rel-1.12.1-0...)

The patch does just that. Also the rom loader gets simplified as all remaining users of the rom loader load the bits at a fixed address so the packing and aligning logic can go away. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1840719 Title: win98se floppy fails to boot with isapc machine Status in QEMU: New Bug description: QEMU emulator version 4.1.50 (commit 50d69ee0d) floppy image from: https://winworldpc.com/download/417d71c2-ae18-c39a-11c3-a4e284a2c3a5 $ qemu-system-i386 -M isapc -fda Windows\ 98\ Second\ Edition\ Boot.img SeaBIOS (version rel-1.12.1-0...)
