There could be a couple of causes for this.
LILO depends on the disk being the same physical and logical device to
allow it to boot - in other words, if the disk was the primary master on
the original machine {HDA}, it must be the primary master on the second
machine - *not* the primary slave [HDB}, secondary master {HDC} or
secondary slave {HDD}.
Because it's the first ide HARD DISK, it'll still try to boot regardless
of where it is in the IDE chain - but it'll fail, because if it's not HDA
{or whatever it was on the old machine}, LILO will be pointing to an
incorrect device.

Usually, the PC bios will default to booting from the SCSI device first,
unless it's been told otherwise - look into the PC bios for something
which reads "Boot order" or maybe "Boot preference" - if it reads
something like "A, C, SCSI", then you have to change it to read "A, SCSI,
C", or even "SCSI, A, C" to get the boot sequence into the right order.
Check out your PC bios - it's unlikely to be the SCSI card which is
affecting the bootup sequence.
