Thanks, that is good to know.

Yep, no problem once I have the card, but I haven't seen any vendors  
mentioning
the  PCI ID; though Intel says which of their many chipsets is on each  
NIC, and
some vendors provide or point to linux drivers.

Syskonnect SK-9Exx/SK-9Sxx (including SK-9E21D 'desktop' adapter) use  
the
Marvell Yukon chipset. The PCI ID of the SK-9E21D is buried in the  
manual as
a screencap (Vendor:1148 Device:9E00 Subvendor:1148 Subsystem:21D0),
which matches what rom-o-matic knows (uses sky2 driver).

The Allied Telesis cards seem to be Broadcom Nextreme II (BCM 57xx)  
but I'm not
sure which ones. The driver they supply is recent (14 Jan 2010) so  
perhaps they use
recent Broadcom chips. The BCM5708 upwards are PCIe and all (except  
5716)
support iSCSI offload, but none appear to have support according to  
rom-o-matic.

Thanks for the pointer, I'd missed that message. Once gPXE supports  
e1000e it
is going to be deployed widely I think, especially in the Windows SAN  
boot role;
I know I am sick of imaging lots of Windows disks.

Interesting. The Realtek 8169 is a PCI part; is it known if it is the  
same interface as
the new PCIe parts (RTL8111 and RTL8168 families)?
