About a month ago, before I read the variuos configuration guides, I built the following rig. I did not change any of the BIOS defaults in re: handling of IRQ assignments. I have had some minor instability problems with occasional BSOD which I am trying to solve. I have reason to believe that I encountered some software corruption along the way and I am considering a clean reinstall of Win 98SE.
Having spent a lot of time pouring over this configuration guide and its links, I still have questions of how best to configure my machine.
Current setup:
8KHA+
BIOS 11/2/01
Athlon XP 1700+ @1.47 (no o/c)
PAL8045 HS
Enermax 431 W PS
2X 256MB Crucial PC2100
2X 60 GB Maxtor 7200 (master and slave IDE 1)
Pioneer 16X DVD (master IDE 2)
NEC Zip drive (slave IDE2)
Plextor 12/10/32 SCSI CDRW
HP scanjet IIcx scanner
Win98 SE
AGP slot GeForce 3 Ti 200
slot 1 empty
slot 2 TB Santa Cruz
slot 3 PCI firewire
slot 4 PCI 56 K Modem
slot 5 Advansys SCSI (for CD-RW and scanner)
slot 6 3-COM NIC
resulting in:
IRQ 3 - TB Santa Cruz
IRQ 4 - Com 1
IRQ 5 - NIC, Modem, USB
IRQ 6 - floppy
IRQ 7 - LPT1
IRQ 8 - CMOS/clock
IRQ 9 - IRQ holder for ACPI
IRQ 10- video card
IRQ 11- SCSI, firewire card
IRQ 12- PS/2 mouse
My questions:
1. With so many PCI cards, it is inevitable that I will be sharing IRQ's. Therefore, is there any point in manualy changing the IRQ assignments in the BIOS as suggested by some?
2. How do I best populate the PCI slots? The documentation for the Santa Cruz and firewire card both suggest ideally not sharing IRQ's, yet there can only be one unshared IRQ (besides the video card) and the configuration guides suggest giving that (slot 2) to the SCSI.
3. Assuming I do not have any immediate interest in overclocking, is there any point in flashing to the new beta bios?
4. If I do manually configure IRQ's, should I disable ACPI?
5. What do I do about the entry "modem use IRQ" in advanced power management?
Thanks for any guidance you can provide.
