Hello, I saw your problem, and I just solve the mine. I install Windows Server 2003 on the Dell R610, via Dell Systems Management Tools.
Then I upgrade the BIOS (from Dell site) And after that, the Debian Lenny could be installed easly. If you need more details, mail-me. -- Tulio Oliveira [email protected] (11) 4063-4230 - São Paulo (21) 4063-4180 - Rio de Janeiro (14) 3413-6588 - Marília (19) 4062-9689 - Campinas (41) 4063-9872 - Curitiba (48) 4052-8762 - Florianópolis (31) 4062-7401 - Belo Horizonte (54) 4062-9112 - Caxias do Sul (85) 4062-9872 - Fortaleza 'Para obter algo que você nunca teve, precisa fazer algo que nunca fez'.
