Hello, I did more search on the keyboard problem, just posted on the forum but here seems to be a better place:
The GPL Gujin bootloader (http://gujin.org) is using the BIOS mouse interface (INT 0x15/0xC2 interface) and as soon as the "set handler" service is initialised (INT 0x15/0xC207) there is a problem with the keyboard: uninterrupted "key present" (INT 0x16/0x01) with dummy keys are reported to be pressed. This never happens with a real PC, and this even happens when the "mouse handler" is only pointing to a "ret far", but does not happens when this assembly service (to set the handler) is patched out of Gujin code. It seems that there is a problem in which handler (IRQ1/IRQ12 i.e. INT 0x9/INT 0x74) is called out of the PS2 controller, when mouse bytes are present. I am using the qemu part of Fedora 7. Someone has an idea of what may happens? I tried to patch/regenerate bochs-2.3/bios/rombios.c because I noted that comment: // TODO : // // int74 // - needs to be reworked. Uses direct [bp] offsets. (?) but I am really unfamiliar with this codebase, and my patch (to read all the mouse data at once on the first call) did not fix the problem. Thanks for any information, Etienne. _____________________________________________________________________________ Ne gardez plus qu'une seule adresse mail ! Copiez vos mails vers Yahoo! Mail
