Platform Confidence Test (PCT) reports SIO error when no floppy drive
is present
Problem
With no floppy drive connected to the onboard floopy controller, the
Comprehensive Test option of PCT revs1.03 and 1.04 when run from either a
CDROM or a Hard Drive (HDD) will report a Super IO error as follow:
"ERROR: SIO308.Verify_ESCD
Resource mismatch between ECSD structure and SIO Registers"
Implication
The PCT utility was developed to run from a floppy disk only. It was designed to
automatically detect the presence of an onboard floppy drive during the
Comprehensive Test option. However, with no floppy dirve present the system
BIOS keeps the onboard floppy controller enabled. During the HW detection
process the PCT checks for the status of the floppy controller only assuming a
floppy drive is present. This causes the SIO test module to fail.
Until the new PCT is available, Intel recomends customers to disregard this error.
Workaround
Add a floppy drive to the system configuration to clear error.
Status
Fixed. Intel has corrected this issue starting with PCT Release 1.05.
5
Unknown Interrupt Error Message during POST
Problem
When there are no bootable media or devices present i.e. no bootable floppy
disk, cdrom disk or hard drive, the following error message may appear during
POST:
"INT 0000006F Unknown Interrupt - HALT !!! (00000010 : XXXXXXXX) "
After posting the error, the machine boots to the EFI shell.
Implication
This anomaly is due to the BIOS not masking an interrupt from the ICH5
correctly with MCH <= C2 stepping. The system will boot to EFI-32 after this
error message posted. An EFI fix has been done in the P05 BIOS and later.
Workaround
Add a bootable media device to system configuration.
Status
Fixed. Intel has correncted this issue starting with production BIOS P05.
6
COM Port B Ring Indicator not terminated correctly.
Problem
On first board productions of the Intel® Server Board SE7520JR2, the RI (ring
indication) pin of the external serial port B, commonly used for modem
applications, was incorrectly terminated. This may result with RI signal not
functioning reliably.
Implication
Modem not supported.
Workaround
None.
