The UNDI API is absolutely atrocious, however, being based on NDIS2 which is widely considered the worst of all the many network stacks for DOS. Additionally, many UNDI stacks don't work correctly when called from protected mode, since the interface doesn't work right. Additionally, UNDI is *ONLY* available after booting from the NIC.
Agreed. But still having a single driver for all the NICs would be simply GREAT for my setup, in which all the PCs will be booted using PXE only. So apart from performance / relilability issues, what are the technical roadblocks in this? I'm sure having a single driver for all the NICs is a feature cool enough to die for. Yes, it might have drawbacks like just pointed out by Peter, but surely a "single driver for all NIC" feature could prove to be great in some systems. But since it does not already exist in the kernel, there must be some technical feasibility isse. Any ideas on this? And any Idea where can I find the Intel's PXE SDK for Linux? I googled for an hour but to no avail. Texts suggest that it was available on Intel Architecture's Lab website which is non existent now. I would appreciate if some one could send me the PXE SDk from Intel, if somebody still has a copy.
