[Qemu-devel] floppy disk

[Benjamin David Lunt]

Hi everyone,

I only recently have started to use QEmu due to a request
on the alt.os.development usenet group.  My OS was not working
on QEmu due to it would not recognize the (emulated) floppy.

After a lot of testing, QEmu does not return the correct
values for a Sense Interrupt command and the Status 0 byte.

After looking over fdc.cc, someone has placed a hack write
where it should return these values.

I am just wondering if this hack is temporary or if it will
be committed as code.

For a more detailed description, QEmu returns the value
0x20 while Bochs, VMware, and real hardware return the
values 0xC0, 0xC1, 0xC2, and 0xC3, for each drive 1 - 4
respectively.

I am asking for more information on this subject.

For more information, please see the thread
