• How to update the PCMCIA driver under Windows 95?

  1. IRQ resources
  The PPC-120/140/150 comes with powerful devices to meet customer demand.
  Otherwise, based on limitation of IBM PC hardware architecture, the IRQ
  resources are lacking for all peripheral devices built in PPC-120/140/150. User
  need to disable some devices never used and releases IRQ resources for the
  others you want to use. The following table lists the relationship between IRQs
  and peripheral devices.
  
  Hardware interrupt Assignment for PPC-120/140/150
  IRQ Device Remark
  IRQ 0 Timer
  IRQ 1 Keyboard
  IRQ 2 Interrupt from 8259 #2
  IRQ 3 COM 2
  IRQ 4 COM 1
  IRQ 5 COM 4
  IRQ 6 Floppy Disk Controller
  IRQ 7 Parallel Port: LPT 1
  IRQ 8 COMS Real Time Clock
  IRQ 9 ESS 1869 Audio Controller
  IRQ 10 COM 3
  IRQ 11 RTL 8139 Network Controller
  IRQ 12 PS/2 mouse
  IRQ 13 Math. Coprocessor
  IRQ 14 Primary IDE Controller
  IRQ 15 Secondary IDE Controller
  ? PCMCIA (TI 1250) Controller Hardware shares IRQ.
  ? IrDA IRQ 3, 4, 5, 10
  ? USB
  By above table, we know two IRQs must be reserved for PCMCIA slots when you
  want to use them. The following paragraph will help you how to update the
  PCMCIA driver for Windows 95.
  
  2. Update Driver
  PPC-120/140 built in a TI1250 CardBus PCMCIA controller. It is too new to
  support by Windows 95(Windows NT 4.0 supports it). So, user need to update the
  driver to let Windows 95 recognizes it. In following example installation
  procedure, the PS/2 mouse and COM3 are disabled and release two IRQs for PCMCIA
  slots. Please refer to your application to disable what devices.
  1. Disable PS/2 mouse and COM3 in BIOS setup menu. When restart PPC-120/140,
  the BIOS reports IRQ10 and IRQ12 have been assigned to PCAMCIA slots.
  2. Under Windows 95, copy CBSS.VxD (Socket Service) and PCCARD.VxD (Card
  Service) to Windows/ System folder.
  3. Copy PCMCIA.INF to Windows/ Inf folder.
  4. Go to Control Panel and double click on system icon.
  5. In Device manager, remove two ? Cardbus bridge?items under "Oth
