I am pretty sure that you need a CD-rom that supports 512 byte blocksizefor this to work in your alpha. Most of them only do 2048 bytes and I havenever had any success with those. The symptoms of not using 512 bytesblocksize have been exactly those you've had. This does not not seemto apply if you have a regular ISO formatted cd.

You should also be able to test the cd's before trying to boot from them.With the cdhdtape written to it is possible to mount the cd just like ifit was a harddrive (with -ro since it is readonly media) and disklabelshould show what slices are on there just like with any regular disk.


Cheers,
Anders

Just for the sake of experimenting, I thought I'd try writing
NetBSD/alpha 5.0's cdhdtape file to CD and booting from it, but so
far it hasn't worked.  The steps I followed are shown below.  The
cdrecord commands were executed on a PC running NetBSD/i386 5.0.  I
used the -v option in the hope it might help to clear up the problem.

I've tried using two different CD-R/W discs in case one was damaged,
and also tried booting a 164LX with the same result as below.

Booting from a hard disk to which the same cdhdfile had been copied
worked fine.

By the way, what's the correct block size to use when writing
cdhdtape to a hard disk with dd, bs=16k as shown in

ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0/alpha/INSTALL.txt

or 18k as shown in

ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0/alpha/installation/diskimage/README.files

Both values seem to work OK.
