OK, gang, I’m stumped. Replaced mobo on system and I suspect an incompatability issue somewhere. Abit VT6X4 (Via 133a chipset), BIOS rev. TG. PIII 500, 128MB PC100 SDRAM. 9.1GB Wide Ultra 2 SCSI HDD on Adaptec 2940-UW Pro adapter. ATI All-in-Wonder 128 Pro PCI, Soundblaster PCI 512, 3Com 3C905-TX NIC.
Reformatted & reinstalled Win98SE. IRQ 14 conflict with IDE controller (needed for ATAPI CD-ROM) and ACPI Holder for PCI IRQ Steering. Tried Via’s Bus Mastering driver, then switched to MS DualPCI IDE Controller, still a resource conflict. By disabling onboard Serial, onboard USB & 2 ACPI Holders, I was able to get IDE controller enabled properly, but when introducing the sound & NIC I had to manually assign free IRQ’s to ACPI Holders andenable them, which sent the display adapter to IRQ 14, thereby disabling the IDE controller again. All further attempts to reassign IRQ’s failed.
I saw someone suggest in the forums to set IRQ’s 14 & 15 to manual (not PnP) in the BIOS. Anyone know if this would make a big difference, or is there an inherent incompatability between Via chipset & ACPI? (I’ve seen messages elsewhere to this effect) Many thanks to anyone with feedback.
