174400 is the RL02, and it's vaguely possible that this is the CSR he meant to type. He describes the disk packs as being Diablos, and RL02 packs do have the same form factor. But if this were the case, then the device he should be trying to boot from would be DL0:, not the DK0: he's been trying so far. 177400 is the RK05, and this is possible too. Of course, we've so little information that this is all just shooting in the wind! ----- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817
