Motherboard is an Asus P5A-B with an M5229 chipset and award bios revision
1003
Evidently I've touch everything in my Award bios (ide modes: auto, 4/2....),
booted from dos with dos drivers... nothing works (only windows?)
I'm more disapointed because somebody says me that his Asus P5A works well
!!?!?! (The ATX version) because of that I've decided to debug the kernel in
the only way i know (i'm new in this kind of enviroments) print some variables
touching a bit the last function of the /drivers/block/ide-dma.c file
(appendix A), the otput of the dmesg command is available at Appendix B , also
here is the result of the dmesg command after booting with loadlin from win 98
(Apendix C)
