MD5 is used in TLS1.0 for RSA signing and random derivation (PRF). See
RFC2246.
(Please note that OpenSSL hasn't been mentioned in this sentence).
SHA256 used for the PRF is available with TLS1.2 only. SHA256 used for
the HMAC is available for some ciphersuites defined for TLS1.2 only (but
I think you could define your own with TLS1.0).

Hi,
We are currently analyzing and understanding the security strength of
the openSSL internal implementation to certify the products.
In version 0.9.8d, TLSv1.0 alone is supported. Can you please answer
the following or provide me with the documentation reference
1.Does openSSL library use MD5 internally for any operation?
2.Can we have SHA256 in the ciphersuite with TLSv1.0?
Thanks,
Venkat
