Note: for install this patch, you must download the last coreboot SVN, and install first the patch posted by Corey Osgood, that includes CN700/C7 and jetway mainboard.
The filo patch is for correct a problem with FILO when tries to find the IDE disk, if more that one IDE interface is on, and no all IDE's are in native Mode. The count of compatibility interfaces are wrong, and not finds the interface that is marked as a IDE 0x0101 or SATA 0x0180 and not all are native, the search of the io base and control, are wrong.
If this is not correct sorry :)))
If in VT8237R have SATA as an 0101 and the IDE too 0101 class, with this patch, works, because counts corectly the unique non native interface IDE, as the first.
NOTE1: in the epia-cn/Config.lb the IDE and SATA are enabled. NOTE2: in epia-cn/auto.c the values of PCI_DEV(0,0x11,0) 0x50 and 0x51 are different, for have IDE and SATA enableds at function enable_mainboard_devices NOTE3: Here is a file base.c that haves a udelay with use of rtdsc NOTE4: another function via_cn_fixup, fixes the use of PCI devices access to the memory. Must be improved, and not use a fixed value. NOTE5: have a change in cn700/raminit.c for configure in CN the memory. NOTE6: vt8237r configures the SATA device as an IDE class 0x0101 must be 0x0180?????
