4 EIDE & SCSI in single box
issues.
HELP! I need to install a SCSI and
IDE Drive in same box.
Issues : -
1) You cannot boot from the SCSI Drive.
Your partition will be in the following order: Primary on Each Physical
IDE Drive, Primary on Each SCSI HD, Extended on each IDE, Extended on each
SCSI.
2) SCSI ID can be set to 0 or 1, and is
only necessary if you are booting from the SCSI Drive, as stated previously,
if you have an IDE Drive, your system will boot from the IDE Drive.
Assuming the EIDE drive is the boot
drive:
A. Should the SCSI controller's BIOS be enabled
or disabled?
Disabled
B. Does the SCSI ID have to be 2 or greater?
Doesn't matter. MUST be 0 or 1 when the SCSI
is controlling, but otherwise don't worry about it; keeping it 0 or 1 should
avoid conflicts with other devices which are virtually NEVER assigned 0
or 1
C. What kind of drivers might be required for
the SCSI drive?
Under Win'95, none -- most common SCSI adapter cards
will be identified just fine by hardware setup; and the devices chained
off of it should also be "found", so long as they're pretty much
"plain vanilla"; and since you're not talking about BOOTING to
the SCSI, then it's not so much of an issue to have REAL mode drivers loaded;
you might want them if your CDROM is also SCSI-based -- that way you'll
be able to access the CDROM from a command-line boot (like if you want
to do a reinstall of Win'95 onto a "clean" HD from a floppy)
-- in that case, you'll need lines like:
CONFIG.SYS
device=aspi8dos.sys /d
device=aspicd.sys /d:aspicd0
AUTOEXEC.BAT
mscdex.exe /d:aspicd0 /L:n /M:12 /s
D. How does the SCSI drive get a drive letter
assigned?
Booting from (E)IDE will give C: (up to F:, depending
on how many drives are hanging off that controller), and SCSI picks up
afterwards -- ie. if you have TWO (E)IDE drives, they will become C: and
D: and then your SCSI letters start at E: -- if you then ADD a drive to
(E)IDE, this will force the SCSI letters to start at F:
E. Can more than one SCSI drive be used?
Sure can (isn't that why you bought SCSI?) -- think
that there can be 6 SCSI HD's (or devices), so long as there's no other
SCSI device attached to that card (one of the seven numbers is obviously
reserved for the SCSI adapter card itself)
F. Does the number of installed EIDE drives matter?
No! You can have up to 4 EIDE devices (up
from the only two from IDE) -- there can be two hardddrives off the primary
channel and two off the secondary (each channel will have a master and
slave for THAT channel) -- while not as extensive a selection as with SCSI,
there can be other devices besides HDs off of EIDE (not IDE, however) --
think there is some limitation of mix&match of what type of device
can be on each channel (that might be changing -- it used to be that people
avoided putting a HD on the same channel as a CDROM drive, since it slowed
the HD down considerably)
