Ciao a tutti,
vi sottopongo un problema che credo sia abbastanza comune, cio'nonostante non ho ad oggi la soluzione pratica.
Spesso con i giochi (Q3 rulez) ho dei blocchi "momentanei" della sk video, cosi' come a volte degli scatti non giustificabili dalla complessita' della scena. Altro particolare : Ogni volta che parto con Q3, la sk audio si "inceppa" per 5 / 6 volte andando in "loop" prima di partire. Mi dicono che dipende dalla sblive 1024 che ha problemi di irq / bus pci. Avreste una soluzione praticabile ?

La mia configurazione :

ABIT KT7A- RAID
SBlive 1024 PCI su slot 6 (slot 5 mi dicono che sulla abit e' da evitare)
RADEON 32 DDR AGP 4X
Scheda di rete PCI 3COM per il modem ADSL
Scheda di acquisizione video firewire

Da bios ho disabilitato entrambe le porte com e la lpt1 per recuperare qualche IRQ. Cio'nonostante, la sk video e la sk firewire condividono l'IRQ 5, anche se ci sono altri IRQ liberi. Ho impostato da bios PnP OS = YES, in quanto ho Win98Se e nessuna scheda ISA. Vi riporto un estratto dal tool PCIList :

--------------------------------------------------------
AGP transfers
--------------------------------------------------------
The AGP aperture is currently set to 64MB.

The system board supports up to 4X AGP transfers. The graphics card supports up to 4X AGP transfers.

AGP 4X transfers are currently enabled.


--------------------------------------------------------
Sideband addressing
--------------------------------------------------------
The system board supports sideband addressing. The graphics card supports sideband addressing.

Sideband addressing is currently enabled.


--------------------------------------------------------
Fast writes
--------------------------------------------------------
The graphics card does NOT support fast writes.




--------------------------------------------------------
AGP revision
--------------------------------------------------------
The graphics card is an AGP 2.0-compliant device, and may not work correctly under Windows 95 or with first-generation AGP system boards. Ensure you have the very latest GART manager (AGP driver) installed.


--------------------------------------------------------
PCI bus hogging
--------------------------------------------------------
The graphics card may be hogging the bus, which could cause problems for other devices like PCI sound cards.


--------------------------------------------------------
Related issues
--------------------------------------------------------
PCIList only queries the system configuration registers. In the event of problems, other things to check to ensure AGP support is enabled and working properly include the following:

- make sure the correct and latest GART manager (AGP driver) for your system board is installed, as well as the latest drivers for your graphics card and DirectX version

- in your system BIOS Setup program, the AGP aperture should be enabled and set to at least 64MB; an IRQ should be assigned to the VGA card; any option referring to spread spectrum should be disabled; and video BIOS and RAM shadowing should be disabled

- if the system has been overclocked to reach 1257 MHz, the AGP clock may now be too high; system memory which otherwise works without errors may be unable to cope with the heavier demands of AGP traffic when running 3D applications

- some AGP features may actually be available in hardware, but be disabled in specific BIOS and/or driver releases, or even by user-configurable software switches (e.g., in the Windows registry)
