Hi, trying to fix these ACPI errors in my DSDT:

Code:

dsdt.dsl   3545:                         0xFFF00000,         
Error    4049 -                                  ^ Length is larger than Min/Max window

dsdt.dsl   5177:                                 0x00000000,         
Error    4043 -                                          ^ Invalid combination of Length and Min/Max fixed flags

dsdt.dsl   5184:                                 0x00000BFF,         
Error    4050 -                                          ^ Length is not equal to fixed Min/Max window


Here is the code:
Code:

3540                     DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
3541                         0x00000000,         // Granularity
3542                         0x00100000,         // Range Minimum
3543                         0xFEBFFFFF,         // Range Maximum
3544                         0x00000000,         // Translation Offset
3545                         0xFFF00000,         // Length
3546                         ,, _Y00, AddressRangeMemory, TypeStatic)

5172                             DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
5173                                 0x00000000,         // Granularity
5174                                 0xE0000000,         // Range Minimum
5175                                 0xE0000000,         // Range Maximum
5176                                 0x00000000,         // Translation Offset
5177                                 0x00000000,         // Length
5178                                 ,, _Y01, AddressRangeMemory, TypeStatic)

5179                             DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
5180                                 0x00000000,         // Granularity
5181                                 0xFEE00400,         // Range Minimum
5182                                 0xFEE00FFF,         // Range Maximum
5183                                 0x00000000,         // Translation Offset
5184                                 0x00000BFF,         // Length
5185                                 ,, , AddressRangeMemory, TypeStatic)


So, I'm scratching my head....any suggestions on what values to use to fix these errors? This is for a Gigabyte GA-MA770T-UD3P motherboard if it helps any.

Range Maximum - Range Minimum + 1 = Length

Range Maximum=0xFEBFFFFF line 3543
Range Minimum=0x00100000 line 3542

0xFEBFFFFF - 0x00100000 + 1 = 0xFEB00000

but on line 3545 Length=0xFFF00000

Code:


5172                             DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
5173                                 0x00000000,         // Granularity
5174                                 0xE0000000,         // Range Minimum
5175                                 0xE0000000,         // Range Maximum
5176                                 0x00000000,         // Translation Offset
5177                                 0x00000000,         // Length
5178                                 ,, _Y01, AddressRangeMemory, TypeStatic)



Since the min range and max range are both 0xE0000000, it seems to me that the length 0x00000000 is correct since there is no range. Why is the compiler complaining about the length?
