with the 3.1.14 version that came precompiled with Slakware 7.0 the computer froze with any hot-swap, independent of the card type, Xircom or Zip100. The modem worked when inserted before booting, the Zip100 showed the same error as under 3.1.15. Now with 3.1.15, the Xircom Modem works fine, the Zip100 not at all. Inserting at boot-time or hot-swapping does'nt make a difference. I always get: ide_cs: ide_register() at 0x100 & 0x10e, irq 5 failed get dev info on socket 1 failed: Resource temporarily unavailable I tried to exclude irq 5, but then I get the same message with another irq number. Please let me know if I should carry out any other tests and thanks for any help you may provide. -ulrich PS: your reply did not reach me as email, though I activated the corresponding button on the form.
