# how to flash LSI SAS 2008 hba dell perc h310 raid jbod card
# for uefi motherboards, must boot uefi and use sas2flash.efi
# select uefi in the moot menu --> launches boof.efi. then:

# official UEFI oprom downloads are now only available from the product page of lsi 8210-8i card
# however we found an un official mirror / off site backup of previous files

# https://www.broadcom.com/products/storage/host-bus-adapters/sas-9210-8i#downloads

# the download filename is: UEFI_BSD_P19.zip
# file inside: md5sum x64sas2.rom Signed/x64sas2.rom 
# bdb478c449a2c3b68874d28506eb8d7a  x64sas2.rom
# 811074a438fe18ebd11cabab584cf91d  Signed/x64sas2.rom

# wheras the P19 main firmware for the 8211-8i variant was seperately available at one time
# it's been mirrored / saved to the following driver site url (at least, for the time being)

# the download filename is: 9211-8i_Package_P19_IR_IT_Firmware_BIOS_for_MSDOS_Windows.zip

# we only flash P19 firmware and P19 uefi oprom, because there are
# known issues with the P20, and situations where it returns many SATA io read/write errors!

# quote source: https://www.reddit.com/r/homelab/comments/6e5vjv/troubles_when_flashing_h200_in_r710/
# either stay on p19 or make sure to get the p20 20.0.0.7 version.. 
# there has been some confusion, because lsi released the p20 firmware, 
# but never the p20 driver for it. p20 Versions lower than 20.0.0.7 had some bugs


# to clear off original dell branding, requires megarec.exe, run in a dos environment

# when booting into freedos on a UEFI motherboard, and in CSM compatibility mode
# it is possible that you may be able to run megarec.exe and see the adaptor
# however when trying to perform any actual operation the program crashes with a page fault
# see example screenshot. This occurs with the default freedos boot option 1
# the solution is to instead select the boot option 4 'safe mode' for freedos

# now disable csm mode. and boot into uefi shell

# set the display text mode to 240 columns and 56 lines

# switch to fs0: drive
fs0:

# mount drives, list files, cd (change directory), and execute .efi programs
# mount ls cd type etc..

# print the device number (enumerator / identifier for multiple caards)

# hard power off, wait for 5 seconds. boot back into efi shell

# flash the p7 intermediate IR firmware. this preserves nvram and also switches from IR to IT mode
# this is a necessary step. otherwise the later P19 IT flashing will fail with 'cannot switch from IR to IT firmware'
