On 100/1000, never 10Mb though. Not to say that the HPs smell like roses, but I would highly suspect bad hardware or a suspect BIOS/PCB revision, etc. in this case. Just my US$0.02, -- Ken. brownfld@irridi.com * besides a quirky arp issue on boot that seemed to go away on its own and wasn't card-specific. And the long-standing I/O APIC issues. ;) On Fri, Feb 01, 2002 at 01:16:15PM -0500, nick@snowman.net wrote: | Odd, I've got an HP LPr with an Ethernet controller: Intel Corporation | 82557 [Ethernet Pro 100] (rev 8). on the riser.
