  We present measurements of the cross-correlation of the triply-ionized carbon
(CIV) forest with quasars using Sloan Digital Sky Survey Data Release 14. The
study exploits a large sample of new quasars from the first two years of
observations by the Extended Baryon Oscillation Spectroscopic Survey (eBOSS).
The CIV forest is a weaker tracer of large-scale structure than the Ly$\alpha$
forest, but benefits from being accessible at redshifts $z<2$ where the quasar
number density from eBOSS is high. Our data sample consists of 287,651 CIV
forest quasars in the redshift range $1.4<z<3.5$ and 387,315 tracer quasars
with $1.2<z<3.5$. We measure large-scale correlations from CIV absorption
occuring in three distinct quasar rest-frame wavelength bands of the spectra
referred to as the CIV forest, the SiIV forest and the Ly$\alpha$ forest. From
the combined fit to the quasar-CIV cross-correlations for the CIV forest and
the SiIV forest, the CIV redshift-space distortion parameter is $\beta_{\rm
CIV}=0.27_{\ -0.14}^{\ +0.16}$ and its combination with the CIV linear
transmission bias parameter is $b_{\rm CIV}(1+\beta_{\rm CIV})=-0.0183_{\
-0.0014}^{\ +0.0013}$ ($1\sigma$ statistical error) at the mean redshift
$z=2.00$. Splitting the sample at $z=2.2$ to constrain the bias evolution with
redshift yields the power-law exponent $\gamma=0.60\pm0.63$, indicating a
significantly weaker redshift-evolution than for the Ly$\alpha$ forest linear
transmission bias. We demonstrate that CIV absorption has the potential to be
used as a probe of baryon acoustic oscillations (BAO). While the current data
set is insufficient for a detection of the BAO peak feature, the final quasar
samples for redshifts $1.4<z<2.2$ from eBOSS and the Dark Energy Spectroscopic
Instrument (DESI) are expected to provide measurements of the isotropic BAO
scale to $\sim7\%$ and $\sim3\%$ precision, respectively, at $z\simeq1.6$.
