This may be the one :
"Adaptec AIC-7860 Ultra SCSI host adapter", /* AIC_7860 */

The kernel entries that correspond are :
CONFIG_SCSI_AIC7XXX=m
CONFIG_AIC7XXX_CMDS_PER_DEVICE=8
CONFIG_AIC7XXX_RESET_DELAY_MS=15000
# CONFIG_AIC7XXX_PROBE_EISA_VL is not set
# CONFIG_AIC7XXX_BUILD_FIRMWARE is not set
# CONFIG_AIC7XXX_DEBUG_ENABLE is not set
CONFIG_AIC7XXX_DEBUG_MASK=0
# CONFIG_AIC7XXX_REG_PRETTY_PRINT is not set
CONFIG_SCSI_AIC79XX=m
And for the aic7xxx_old :
CONFIG_SCSI_AIC7XXX_OLD=m
So, both are built as modules, and since we have to use a 3 floppy set
for miboot anyway, it should be ok to use them :
First flopyy : minimal kernel
Second floppy : minimal root image, with floppy drivers.
Third floppy : rest of the drivers, maybe more than one floppy.
So there may be support for this in the future.
