Subject: [gPXE] Booting MS-DOS using gPXE/iSCSI: C: drive is read only

I just managed to setup my diskless DOS boot using gPXE and iSCSI
DOS (6.22) boots OK, even old games (ancient doom) that are present in
the 
DOS disk image start fine.
However, I can't write anything to c:\ !
executing:
echo 1 > c:\test.txt
results in general failure error, and a 0 bytes file on disk


dnsmasq/ietd on centos 5.3.
used  iSCSI target is writable when connected from XP/Windows7
Used rom-0-matic to download stable ISO image, for RTL8139


Any hints welcome.....

"ACS,"

Are you connecting multiple clients to the same iSCSI target at the same
time?  The FAT filesystem is not designed with multiple simultaneous
clients in mind, as far as I know.  If you have a Windows XP and/or a
Windows 7 and/or a DOS client connected at the same time, you could
experience filesystem corruption and strange errors like "general
failure."

Also, see if your iSCSI target software allows for multiple clients.  It
could be that you need to disconnect all clients first, then maybe a
single client will have better luck.
