**M1535/D        South Bridge                                        ?
***Info:
The  M1535  provides the  highest  integration  south bridge  solution
between PCI bus and Peripheral buses for personal computer systems. It
includes audio, high-speed modem, Super  I/O and Fast IR integrated in
to  one chip to  complement any  one of  ALi’s North  Bridge solutions
namely M1541, M1621 and M1631.

The  M1535 is  PCI spec.   2.2 compliant.   It provides  steerable PCI
Interrupts for PCI device Plug-and-Play, it has up to 8 PCI interrupts
routing, it  has level to edge  trigger transfer. It  has enhanced DMA
controller.  It  provides 14 interrupt channels  as Interrupt Control-
ler.  It provides 8254 Compatible timers for system timer, Refresh Re-
quest,  Speaker  Output  use.  It  has  7  DMA  channels that  can  be
arbitrarily programmed as distributed  channels.  It provides 1 PC/PCI
DMA channel interface.  It supports serialized IRQ in quiet/continuous
mode.  It  supports Plug-and-Play.  It  has built-in PS2  Keyboard and
mouse controller.  It provides hot plugging events detection.

The M1535 also provides the  best power management solution. The M1535
integrates  ACPI   support,  deep  green   function,  2-channel  Ultra
DMA-33/66  IDE bus  master  controller, 4-port  USB controller,  SMBus
controller,  Super  I/O, audio  system  and  software  modem into  one
27mmx27mm BGA  (Ball Grid Array)  chip. 

Further  more, the  M1535  is  designed to  meet  the requirements  of
desktop, mobile PCs.
