2009-01-24Floppy: Properly handle Sense Interrupt Status after FDC Resetblueswir11-12/+18
Original text below. Attached is a patch that changes how the emulated floppy controller replies to Sense Interrupt Status commands immediately after a controller reset. The specs state that after a Reset the 82078 goes into polling mode which needs four Sense Interrupt Status commands to be issued afterwards to clear the status of each drive. Currently we always respond to Sense Interrupt Status with a SEEK END instead of POLLING. This causes a problem with the SCO Openserver installer which is expects a POLLING state after reset. This patch returns a POLLING status for four Sense Interrupt Status requests immediately after a controller reset. This approach mirrors the way Bochs handles this situation. With the attached patch applied Openserver gets further when trying to load storage drivers from the floppy disk (blocked by another issue, patch on its way). I have successfully tested the floppy drive on the following OSs after applying this patch: Windows 98, Windows XP SP2, Linux x86 (SysRescCD 1.1.3 and Ubuntu 8.10).

2008-05-01FDC: Fix data transfer len (Hervé Poussineau)blueswir11-2/+2
In floppy controller, transfer data len is not correctly calculated. We should read up to the last sector specified by the caller, and not up to the last sector of the floppy. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4294 c046a42c-6fe2-441c-8c8c-71466251a162
2008-05-01FDC: Fix buffer overflow (Hervé Poussineau)blueswir11-2/+4
In floppy controller, programming PIO writes which are more than one sector long leads to a buffer overflow of the fdtrl->fifo[] array. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4293 c046a42c-6fe2-441c-8c8c-71466251a162

- Stores controller state in MSR register instead of internal state field. This simplifies the fdctrl_read_main_status() function, which may be called in some tight loops. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4286 c046a42c-6fe2-441c-8c8c-71466251a162
