Re: Nagging problem with DOS app under Win2k on ABit/Matrox

******************** IRQ SUMMARY ********************
IRQ Usage Summary:
(ISA) 0 System timer
(ISA) 1 Standard 101/102\ufffdKey or Microsoft Natural PS/2 Keyboard
(ISA) 3 Communications Port (COM2)
(ISA) 4 Communications Port (COM1)
(ISA) 6 Standard floppy disk controller
(ISA) 8 System CMOS/real time clock
(ISA) 9 Microsoft ACPI\ufffdCompliant System
(PCI) 11 Matrox Millennium G450 DualHead \ufffd English
(PCI) 11 VIA USB Universal Host Controller
(PCI) 11 VIA USB Universal Host Controller
(PCI) 11 Creative SB Live! Basic (WDM)
(PCI) 11 3Com EtherLink XL 10/100 PCI TX NIC (3C905B\ufffdTX)
(ISA) 12 Logitech\ufffdcompatible Mouse PS/2
(ISA) 13 Numeric data processor
(ISA) 14 VIA BM Ultra DMA Channel
(ISA) 15 VIA BM Ultra DMA Channel

I'll have to rummage around the case when I get a chance to see which cards are plugged in where, and see if I can easily put the Matrox on a different IRQ. 10 perhaps? PCI slot 1 shares IRQs with the AGP card. PCI slot 4 and the USB controllers share an IRQ.

The USB hub on this thing has always been more flakey than I'd like (I usually reboot after using the 6-in-1 reader with my MemoryStick to make sure things don't lock up, etc.).

I may try removing the SB Live card and even the USB stuff and see if that helps.

Thanks for putting me on this line of attack. It may take me a few days to try these various things. Please keep any suggestions coming.

Cheers,
Scott.

Everything else can share. Peter [link\|http://www.debian.org\|Shill For Hire] [link\|http://www.kuro5hin.org\|There is no K5 Cabal] [link\|http://guildenstern.dyndns.org\|Blog]

The solution was by trial and error, which is worse even than those early days of Plug and Pray. Windows seems to do better at this dance than Linux. Don't know why. I always have the sinking feeling that the wrong choice impairs overall performance, but have no way to verify one way or the other. -drl
