I am going to assume you have either a Sparcstation 10 with an SBUS
hme card, or you really have an Ultra 10 with the built-in hme
interface[1].

Interactively:

# ndd -set /dev/hme instance [0|1|2|3] 
(0 -3 depending on which interface you are setting, you can omit this
step if there is only one)

# ndd -set /dev/hme adv_autoneg_cap  0
# ndd -set /dev/hme adv_100fdx_cap   1
# ndd -set /dev/hme adv_100hdx_cap   0
# ndd -set /dev/hme adv_10fdx_cap    0
# ndd -set /dev/hme adv_10hdx_cap    0

Or put this in the /etc/system file:

*
* forces 100-base-T Full Duplex, no autonegotiation,
* on all hme interfaces
*
        set hme:hme_adv_autoneg_cap=0
        set hme:hme_adv_100fdx_cap=1
        set hme:hme_adv_100hdx_cap=0
        set hme:hme_adv_10hdx_cap=0
        set hme:hme_adv_10fdx_cap=0

[1] A SparcStation 10 wouldn't normally have a 100Mb/s interface, do
you have an SBUS hme or qfe card installed in one, or is it that you
actually have an Ultra 10 and called it a Sparcstation 10?

Ultra 10 != Sparc(station) 10,   Ultra 5 != Sparc(station) 5
