+At this time, For acpi support We got
+1. support AMK K8 SRAT --- dynamically (LinuxBIOS run-time)  (src/northbridge/amd/amdk8/amdk8_acpi.c)
+2. support MADT ---- dynamically (LinuxBIOS run-time)  (src/northbridge/amd/amdk8/amdk8_acpi.c , src/mainboard/amd/serengeti_cheetah/acpi_tables.c)
+3. support DSDT ---- dynamically (Compile time, LinuxBIOS run-time, ACPI run-time) (src/mainboard/amd/serengeti_cheetah/{dx/*, get_bus_conf.c}, src/northbridge/amd/amdk8/get_sblk_pci1234.c)
+4. Chipset support: amd8111, amd8132
+
+The developers need to change for different MB
+
+Change dx/dsdt_lb.dsl, according to MB layout 
+	pci1, pci2, pci3, pci4, ...., pci8
+	if there is HT-IO board, may use pci2.asl.... to create ssdt2.c, and ssdt3,c and ssdt4.c, ....ssdt8.c
+
+Change acpi_tables.c
+	sbdn: Real SB device Num. for 8111 =3 or 1 depend if 8131 presents.  ---- Actually you don't need to change it, it is LinuxBIOS run-time configurable now.
+	if there is HT-IO board, need to adjust SSDTX_NUM...., and preset pci1234 array. acpi_tables.c will decide to put the SSDT on the RSDT or not according if the HT-IO board is installed
+
+Regarding pci bridge apic and pic
+	need to modify entries amd8111.asl and amd8131.asl and amd8151.asl.... acording to your MB laybout, it is like that in mptable.c
+
+About other chipsets, need to develop their special asl such as 
+	ck804.asl  --- NB ck804
+	bcm5785.asl or bcm5780.asl ---- Serverworks HT1000/HT2000
+
+use a to create hex file
+use c to delele hex file
