Cabrillo Chassis
Hot Swap Backplane Controller (HSC)
Firmware Version 0.63
(Bootblock Version 0.20)
Release Notes - July 30, 1999
Introduction.
This document applies to the firmware used in the Intel Cabrillo-C
server chassis hot swap SCSI backplane. At the time of release, this
firmware supports two Intel server baseboards, the SC450NX (Sitka) and
the C440GX+ (Cypress).
*** WARNING ***
Do NOT upgrade the C440GX+ (Cypress) server BIOS to version 4.0 or later
without following the instructions in this document.
There is a serious issue regarding the use of HSC firmware in
conjunction with the Cypress baseboard BIOS version 4.0 and later.
Cypress users are urged to read the dependencies section before
upgrading either the BIOS or the HSC firmware. This warning does NOT
apply to the Sitka baseboard.
A note about DCS numbers.
The DCS numbers used in this document refer to Intel's internal defect
tracking database. These numbers are generally not meaningful outside of
Intel, they are included in these release notes as part of Intel's
tracking and correction process.
Changes since previous version (HSC 0.62).
1. Fixed DCS 18134. SCSI BIOS hangs when warm booting windows.
Changes since previous version (HSC 0.61).
The following performance improvements have been made:
1. The SCSI selection time has been reduced from approximately 200
milliseconds to approximately 30 microseconds.
2. The time required for SCSI phase changes has been reduced from
approximately 2 milliseconds to approximately 500 microseconds.
3. The HSC now transfers SCSI management information and commands to
and from the host controller approximately 4X faster than previous
versions. Note that this does not affect the speed of file transfer
to and from the drives except for the fact that the SCSI BIOS will
spend less time talking to the HSC during such transfers.
4. Several errors in clocking data to/from the host were corrected, as
was handling of timeout errors. This change resolves Sitka DCS 16137
and Cypress DCS 17876.
Dependencies.
SC450NX (Sitka):
No dependencies are known. This firmware was tested in conjunction
with Sitka BMC firmware version 0.28 and BIOS 10. This firmware
should also work well with BMC 0.27.
C440GX+ (Cypress):
Cypress BIOS version 4.0 and later incorporates a new version of the
Adaptec SCSI BIOS for the on-board SCSI controller. This SCSI BIOS
is incompatible with prior versions of the hot swap controller
firmware.
If the BIOS is upgraded to version 4.0 or later while running any
version of HSC firmware prior to 0.62, the server will not boot
after the BIOS upgrade if any drives are present in the hot swap
bay.
Users must first flash in the HSC 0.62 firmware and then flash the
BIOS up to version 4.0 or later.
No other dependencies are known. This firmware was tested in
conjunction with Cypress BMC firmware version 1.04 and BIOS 4.0.
Cabrillo HSC firmware release history.
Note: There were no versions 0.56 through 0.60 of the Cabrillo HSC
firmware. The jump in version numbers is due to shared code with
other HSC products.
HSC Version 0.61 (Bootblock version 0.20), July 16, 1998:
DCS 12723: The slot LEDs can blink at a fast or slow rate to indicate
various conditions. Originally "slow" was approximately 1 Hz and "fast"
was 2 Hz. The fast rate has been increased to 3 Hz to make it more
obvious to the user.
DCS 13284: The HSC was spending approximately 200 milliseconds in the
Message In phase before going to Bus Free. This time was reduced to
approximately 2-3 milliseconds.
The I2C bus communication code was upgraded to avoid a potential loss of
messages when the I2C retry was set to 0. No known cases of these
problems have been documented for this firmware, this is a precautionary
upgrade only.
HSC Version 0.55 (Bootblock version 0.20), May 28, 1998:
DCS 12724: The HSC was handling the SAF-TE "Unconfigured Flag" (Write
Device Slot Status command, byte 0, bit 7) incorrectly. The HSC would
set this bit even when a drive was prepared for operation. The HSC now
only sets this bit when a drive is inserted.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
