No, ksh is software, but a softare update may not update ksh. As fpmurphy mentions there may be more than one firmware program. The V240 server on my desk right now has OBP and ALOM which are both firmware. This is why we should speak of an uptime to OBP or an update to ALOM. Terms like "software update" or "firmware update" don't really convey much information.
And OBP does not store stuff in EEPROM. When you make a change at the ok prompt you are actually changing the NVRAM. The nvram is a chip with a little battery built into the chip. When the battery dies, so does the data in the chip. OBP continues to live in EEPROM and with a lot of effort you can boot a box in this condition. To confuse the issue, Sun has a program which can be run as root called eeprom. eeprom displays the stuff in nvram. I would love to know why they called it "eeprom".
It's been a while since I updated OBP, but I remember that I have to pop the cover off and flip a switch to make EEPRPOM updatable. Then after the update I flipped it back. (Or maybe it was a jumper?) Anyway EEPROM is usually fixed in value.

FTDI-EEPROM(1) General Commands Manual FTDI-EEPROM(1)
NAME
ftdi_eeprom - Tool for reading/erasing/flashing FTDI USB chip eeproms
SYNOPSIS
ftdi_eeprom [commands] config-file
DESCRIPTION
ftdi_eeprom is a small tool for reading/erasing/flashing FTDI USB chip eeproms. It uses libftdi to access the chip, so you will need to
have the required permissions on the device.
The ftdi_sio module should not be loaded. You can prevent it to be automatically loaded by adding it to /etc/modprobe.d/blacklist.
You have to unplug and replug your device to get the new values to be read. Otherwise, you will still get the old values.
COMMANDS
--read-eeprom
Read eeprom and write to -filename- from config-file.
--erase-eeprom
Erase eeprom.
--flash-eeprom
Flash eeprom.
CONFIGURATION FILE
The configuration file contains a list of key-value pairs which will be used to flash an FTDI USB chip eeprom. Comments start with #. The
beginning of such a file might look like the following:
vendor_id=0x0403 # Vendor ID
product_id=0x6001 # Product ID
max_power=0 # Max. power consumption: value * 2 mA. Use 0 if self_powered = true.
###########
# Strings #
###########
manufacturer="ACME Inc" # Manufacturer
product="USB Serial Converter" # Product
serial="08-15" # Serial
The example configuration file that could be found in /usr/share/doc/ftdi-eeprom/examples is quite well commented so you should be able to
use it as a basis. The following keys are supported:
vendor_id
Set the vendor ID of the device. This value could be entered in decimal or hexadecimal form, and should be in the range 0-65535 or
0x0000-0xffff, respectively.
product_id
Set the product ID of the device. This value could be entered in decimal or hexadecimal form, and should be in the range 0-65535 or
0x0000-0xffff, respectively.
max_power
Set the maximum current the device will use, in 2 mA unit. Use 0 if self_powered = true.
manufacturer
Set the manufacturer string which normally holds the name of the manufacturer.
product
Set the product string which normally holds the name of the product.
serial Set the serial string which normally holds the serial number of the product.
self_powered
Specify if the device is self-powered or not. The value should be true or false.
remote_wakeup
Specify if the device supports remote wake-ups. The value should be true or false.
use_serial
If this value is set to true, the serial string will be used. Otherwise the default serial string will be used.
BM_type_chip
This value have to be set to true if you are using a BM chip.
in_is_isochronous
If set to true this option specify that the input endpoint is in isochronous mode.
out_is_isochronous
If set to true this option specify that the output endpoint is in isochronous mode.
suspend_pull_downs
If this value is set to true the pull downs are enabled during suspend for lower power consumption.
change_usb_version
This value has to be set to true if you want to force the USB version using the usb_version key. Otherwise the default USB version
will be used.
usb_version
Set the USB version of the device. The change_usb_version value has to be set to true.
filename
Specify a filename if you want to dump the content of the eeprom into it.
