Here I get
$ md5sum debian-testing-i386-netinst.iso
07b6034367c171526c4fbcdf0851162c
debian-testing-i386-netinst.iso
166703104 Byte, downloaded with wget
Funny, though, that it runs properly for all the rest of the install. I went through until the network was to be configured.
I'll try another download.
Okay, back to square one.
$ md5sum debian-testing-i386-netinst.iso
66e653ba924329df7029c796b4065bed debian-testing-i386-netinst.iso
(20070304)
does not find a network interface card.
The two-year-old 20050305 (incidentially 2 years) does find a NIC and installs nicely.
Also to repeat: I have by now booted to a variety of Knoppix, DSL, harddisks.img, OLPC. No problem.
What next ?
