arthur-p, FIXED!! The problem was that the default iasl4 compiler in MacIASL 1.3 (252) is really old: 2010-03-31 So I looked for a more recent iasl (version 20141107-64 [Jan 2 2015]), then put it in MaciASL/Contents/MacOS, renaming it to iasl4. Now, once I insert DTGP and apply Pjaml's Intel Series-9 Generic fixes, my dsdt.aml compiled fine for the first time. I wish it was mentionned somewhere to update the iasl if there are persistent errors that don't seem fixable. Thanks.

arthur-p, thanks for the prompt response and also for the useful tips. I got your dsdt. Strange, but on my two different Mac OS X installs (Yosemite and Mavericks), it still gives me those errors when compiling with MacIASL 1.3 (252) with ACPI 4.0 (6236) : Error 4096 - syntax error, unexpected PARSEOP_ZERO (8527) : Error 4096 - syntax error, unexpected '}', expecting '(' (8588) : Error 4096 - syntax error, unexpected '}', expecting '(' (8702) : Error 4096 - syntax error, unexpected '}', expecting '(' (8710) : Error 4096 - syntax error, unexpected '}', expecting '(' (8718) : Error 4096 - syntax error, unexpected '}', expecting '(' (9044) : Error 4096 - syntax error, unexpected PARSEOP_IF (10877) : Error 4096 - syntax error, unexpected PARSEOP_ARG0 (13610) : Error 4096 - syntax error, unexpected '}', expecting '(' (14012) : Error 4096 - syntax error, unexpected PARSEOP_IF (15902) : Error 4096 - syntax error, unexpected $end 2/14/15, 3:23:34 PM, Compilation complete. 11 Errors, 0 Warnings, 0 Remarks, 0 Optimizations

I have an Asus H97I-Plus. There's originally 11 errors in the dsdt. Using PJALM's Intel Series-9 Generic Fixes and inserting DTGP in MaciASL, the errors drop to 4. I can't fix the remaining 4 errors.
