IRQ's and ISA modems conflicting.

IRQ's and ISA modems conflicting.

3 modems installed in a Proliant 1600, Com1/irq4, Com2/irq3, Com3/Irq5. All ISA, all USR 56k modems. Tried the same config with 2 internals (set to com3 and 4) and an external on com1 (or com2) which resulted with the same errors. (addt. note. the 2 external com ports were enable/disabled for the proper config)

My end result is still the same. Com1 and Com3 want to use IRQ4. I can't seem to modify it in the OS. Returns with Resource unavailble in the device manager. CPQ Diag reports that COM1 and 3 are using IRQ4. Flashed the Bios to latest rev as well. The exact error in the device manager is, "This device cannot find enough free resources that it can use. (Code 12)"

What's up? Anyone else run into this?
