Hi Paul! > On my 701, IRQ 10 goes to the audio. You could've been conflicting with the > audio. But that really is bad service on Panasonic's part. Speaking of IRQ's on the ThinkPad 701 -- Mine is presently configured as follows: IRQ map: 1 Standard 101/102-Key or Microsoft Natural Keyboard 2 Programmable interrupt controller 3 Panasonic KXLC002 (Panasonic 4X CD-ROM) 4 IBM ThinkPad 701 Internal Modem 5 LPT2 (Canon BubbleJet BJC-70 printer) 6 Standard Floppy Disk Controller 7 LPT1 (Logitech ScanMan PowerPage scanner) 8 System CMOS/real time clock 9 ESS588 AudioDrive 10 Xircom CE-IIps CreditCard Ethernet Adapter 11 theoretically available 12 Logitech PS/2 Port Mouse (Logitech TrackMan Marble trackball) 13 Numeric data processor 14 Standard IDE/ESDI Hard Disk Controller 15 theoretically available I'm running Windows 95 OSR2 from a 2.1 gig HD. I have applied the Flash BIOS upgrade from IBM. I have the Communications Port (conventionally COM2) and the IBM ThinkPad Infrared Port (COM2) disabled because they want to use IRQ 3. In this configuration, I have to plug my trackball into the PS/2 port. As a consequence, I am unable to use the middle button which is supported by the driver only when the trackball is accessed via a serial port. So I want to use the Communications Port (re-enabled and configured to COM2 via the CMOS setup) to access the trackball. That means the Panasonic CD-ROM would have to use a different IRQ. It's choices are 3,4,7,9 and 10. I could use IRQ 10 for the CD-ROM without conflict if I could relocate the Xircom network adapter. It's choices according to the manual are 3,4, 7,9,10, 11, and 15. If I could assign IRQ 11 or IRQ 15, I would be home free to configure the rest of the IRQ's the way I want. However, when I got to Control Panel/System Properties/Xircom CD-IIps CreditCard Ethernet Adapter/Resources and attempt to change the IRQ, I find that Windows 95 OSR2 limits my selection to 3, 4, 7, 9 or 10. Neither 11 or 15 are not offered as viable options. If I attempt to manually enter 11 or 15, Windows tells me that the setting is not valid for this device and automatically chooses IRQ 3 instead. Paul, can you (or anybody else reading this) tell me how to use IRQ 11 or 15 for the Xircom network card given this situation? My suspicion is that this is a Xircom driver related problem, but that being said what can I do about it? Robert W. King I'm an ingenieur, NOT a bloody locomotive driver!
