In core.cpio/etc/init.d/tc-config there are boot options - parameters (asign a value) and switches:
waitusb lang kmap tz desktop ntpserver icons noicons user home tcvd opt swapfile resume host nfsmount tftplist httplist aoe nbd mydata pretce xvesa rsyslog blacklist iso
nozswap nofstab nortc syslog noutc nodhcp text xonly superuser noswap secure protect cron xsetup laptop base showapps norestore noautologin pause
But not all boot options are listed in files TinyCore-7.2.iso/boot/isolinux/ files f1/f2/f3/f4 or /usr/share/doc/tc/bootOptions.txt
The missing options are: cde icons tcvd resume ntpserver nfsmount tftplist httplist aoe nbd pretce rsyslog nofstab nortc xonly
cde: read-only "tce" folder, like for CD/DVD
resume: partition to wake up from hibernate?
icons: icon manager name?
tcvd: loop-mount a ext2 formatted FILE as /dev/tcvd (storage) DEVICE, qemu?
nbd: network block device on server, qemu?;
aoe (ATA over Ethernet?)
ntpserver / nfsmount / tftplist / httplist: boot from network server
pretce: Preload drivers needed for tce/opt/home on lvm/RAID
rsyslog / nofstab / nortc /xonly : debugging ?
Could we have a new small file /boot/isolinux/f5 with them?
